Vincent Kompany joined Manchester City in August 2008 – a little more than a week before the club's trajectory was irreversible changed by Sheikh Mansour's takeover.

The centre-back position, where long-serving club captain Kompany excelled and became a club great, has become a focus for the owner's transfer market millions over the intervening years.

However, there have been more expensive misses than hits, with City's struggles after Kompany's departure last year underlining how subsequent centre-back additions have rarely been anywhere near as successful.

Bournemouth's Nathan Ake is set to be the next man into the building, with City reportedly having agreed a £41million fee for the Netherlands international.

Here, we look at the major centre-back signings made by City during the Abu Dhabi era and how they panned out.

KOLO TOURE (ARSENAL £14M, JULY 2009)

A former title winner with Arsenal, Toure was given the captain's armband by Mark Hughes as club stalwart Richard Dunne was ushered out of the door. The Ivory Coast international struggled for consistency, however, and became a back-up option under Roberto Mancini. Arguably his most significant contribution to City's success was his mere presence encouraging brother Yaya to make the move to Manchester.

JOLEON LESCOTT (EVERTON £22M, AUGUST 2009)

Like Ake now and plenty of others in between, the fee City paid Everton for Lescott brought snorts of derision. But the England international established a rock-solid partnership with Kompany that underpinned the 2011-12 Premier League title triumph. City have never appeared quite so settled at centre-back since their alliance broke down the following year.

JEROME BOATENG (HAMBURG £10.5M, JUNE 2010)

Before going on to become one of Europe's elite central defenders at Bayern Munich, Boateng endured an unhappy year in Manchester. Primarily a right-back at that stage of his career, he found his path to the first team blocked by Micah Richards and Pablo Zabaleta and failed to settle.

STEFAN SAVIC (PARTIZAN £6M, JULY 2011)

Given he was fourth-choice in a season when Kompany and Lescott excelled, it was remarkable how quickly Savic carved out a reputation as an accident-prone liability. A year after signing him, Mancini had lost faith and decided to cut his losses. The steady hand in Atletico Madrid's formidable backline today is a player utterly transformed.

MATIJA NASTASIC (FIORENTINA £12M, AUGUST 2012)

Savic served as a makeweight in the deal to bring Nastasic to the Etihad Stadium. He performed impressively during a largely forgettable 2012-13 campaign, for which Mancini paid with his job. Successor Manuel Pellegrini did not much fancy Nastasic, with injuries further compromising the Serbia international before he moved to current employers Schalke in 2015.

MARTIN DEMICHELIS (ATLETICO MADRID £4.2M, SEPTEMBER 2013)

A loyal lieutenant for Pellegrini, Demichelis left Atletico Madrid without playing a game when the opportunity to reunite with the Chilean coach arose. Long of hair and short of pace, his introduction to the Premier League was fraught and Marcus Rashford skinning him to win a 2016 Manchester derby gave his City career a clanging footnote. However, the Argentina international's experience and steel was vital as the Blues edged out Liverpool in a knife-edge 2013-14 title race.

ELIAQUIM MANGALA (PORTO £42M, AUGUST 2014)

Unperturbed by a massive transfer fee, Mangala was majestic on his debut as 10-man City battled to a 1-1 draw against Chelsea. To be blunt, he never reached those levels again and was rarely close – a slapstick own goal in his next outing at Hull City proving far more representative of what was to come. A popular squad member, Mangala came up short in terms of form, fitness and temperament to unfortunately stand as one of the biggest transfer flops in Premier League history.

NICOLAS OTAMENDI (VALENCIA £32M, AUGUST 2015)

Mangala's struggles sent Pellegrini back into the transfer market for another big-money addition. Otamendi proved scarcely more reliable and the duo generally needed to be watched through one's fingers when paired together. Nevertheless, the Argentina defender's dogged determination saw him become a mainstay during the 100-point season under Pep Guardiola in 2017-18, when he deservedly won a place in the PFA Team of the Year. His error-strewn efforts since have worn increasingly thin.

JOHN STONES (EVERTON £47.5M, AUGUST 2016)

A flagship signing ahead of Guardiola's first season, Stones appears set for the exit door having failed to realise his undoubted potential. He oozed class during the early stages of back-to-back Premier League successes over the previous two seasons, although he tellingly spent large chunks of both run-ins on the sidelines. Injuries have not helped and Guardiola appears to have lost trust in a man who once looked set to be synonymous with his reign.

AYMERIC LAPORTE (ATHLETIC BILBAO £57M, JANUARY 2018)  

For now, Laporte remains City's most expensive central defender and the Frenchman has given considerable bang for their buck after the costly folly listed above. As important to City for his precise and varied range of left-footed playmaking from deep, Laporte is Guardiola's defensive rock. When his cruciate knee ligament injury last August followed a failure to replace Kompany, the writing for 2019-20 was on the wall.

Valencia defender Eliaquim Mangala was taken aback by his coronavirus diagnosis and has still not experienced any symptoms as he continues 14 days in isolation.

Mangala was one of five first-team players from the Spanish club to test positive for COVID-19, with Ezequiel Garay and Jose Gaya the other players from that group to have confirmed their diagnoses.

On Monday, Valencia announced 35 per cent of all tests carried out on people associated with the club had come back positive.

Speaking to L'Equipe, Mangala said: "On Friday at the club, we did some tests, simple ones. I didn't have any symptoms, I was just like every day.

"So, when Sunday morning the doctor told me I was positive, I was shocked. I thought it was a joke at first. But when he talked about quarantine, for 14 days, staying away from my kids, I understood it wasn’t a joke."

Mangala detailed how he has managed to maintain a training routine within the family premises.

"I'm quarantined at home. I’m lucky, I have a house where my family can remain isolated," he explained.

"There is one floor where I stay, and my family is upstairs. We’re trying to avoid each other as much as possible.

"My day is simple : I don’t have any symptoms, so I can continue to train. They [Valencia] gave us a schedule. 

"With a mask, I go out in my garden to keep training. And then I watch documentaries, movies, I play video games. There’s Netflix, I read as well."

Spain is the second-most affected country in Europe by the coronavirus pandemic, with 11,178 reported cases and 491 deaths.

The coronavirus pandemic is still raising questions across sport, even with the global calendar decimated by cancelled and postponed events.

Coronavirus has, according to official figures, caused around 6,500 deaths from approximately 170,000 confirmed cases worldwide.

As the pandemic continues, there are going to be some big decisions made in the world of sport over the coming week, with UEFA's 55 members set to come together – via video conference – on Tuesday.

The fate of this season's Champions League and Europa League will be up for debate, while Euro 2020 is also to be discussed.

Here is a look at the latest developments:

 

Ahead of Tuesday's meeting with UEFA, Italian football federation (FIGC) president Gabriele Gravina confirmed he will call for Euro 2020 to be postponed, in the hope that might allow the Serie A season to be finished in June.

This proposal will likely be backed by LaLiga boss Javier Tebas, who is convinced the top-flight season in Spain will be completed. Swiss FA president Dominique Blanc, meanwhile, has confirmed he has coronavirus.

It is not yet clear what will happen in the Premier League, with the teams set to reconvene for another meeting on Thursday and, after coming under criticism for stating that the season should be considered "null and void", West Ham vice-chairman Karren Brady defended her comments.

"The Premier League and EFL are doing all we can to ensure the season is finished. Including suspending games, isolating players, and if required playing games behind closed doors and into the summer months," she wrote on Twitter.

"My point was safety of fans, players, staff come first and if the remaining games just cannot be played the only fair and reasonable thing is to declare [the] season null and void."

In a newspaper column, Wayne Rooney backed the decision to postpone fixtures in England, but criticised the Premier League and EFL for taking so long to make the call.

More players have confirmed they have tested positive for COVID-19.

Valencia defender Ezequiel Garay became the first LaLiga player to be named as having the illness, with the club adding four more members of the first-team playing and coaching staff had also tested positive.

Valencia's former Manchester City defender Eliaquim Mangala confirmed later on Sunday that he was one of those with the virus.

In Serie A, Sampdoria's Omar Colley posted a video to his official Instagram account in which he refuted his club's claim that he too had received a positive test result.

Meanwhile, Manchester United's Paul Pogba joined the raft of sports stars pledging to support people during the crisis, as he launched a fundraiser to mark his 27th birthday.

In France, Paris Saint-Germain announced they had extended the suspension of all club operations until March 18.

In the United States, Utah Jazz center Rudy Gobert – the first NBA player to be diagnosed with coronavirus – provided a positive update on his recovery, while also stating: "I wish I would have took this thing more seriously and I hope everyone else will do so because we can do it together."

Not all sport has been postponed just yet, with rugby league in both Britain and Australia continuing for now.

In Super League, Castleford Tigers ran out winners over defending champions St Helens, though in the National Rugby League (NRL), Melbourne Storm's Cameron Smith called for the competition to be suspended.

Round two is set to go ahead next week, albeit behind closed doors, while New Zealand Warriors have elected to remain in Australia rather than return to Auckland, where they would have to self-isolate for 14 days.

Eliaquim Mangala confirmed he has contracted coronavirus, but the Valencia defender said he is "feeling good".

Valencia team-mate Ezequiel Garay – who was due to miss the rest of the season due to a ruptured anterior cruciate ligament (ACL) – became the first LaLiga player to confirm a positive COVID-19 test on Sunday.

The Spanish club later released a statement, revealing five members of the first-team playing squad and coaching staff had been diagnosed with coronavirus – though they did not name Garay or Mangala.

Former Manchester City centre-back Mangala, however, announced via social media he was one of five Valencia players to have tested positive.

"I knew today that I am #Coronavirus positive," Mangala, who has only made four LaLiga appearances this season, said in a Twitter post.

"I'm feeling good and I have no symptoms associated with the virus. However, I am confined in house and separated from my family.

"I learned that we can carry the virus without having symptoms, that's why I recommend everyone to follow the confinement measures and avoid contact with other people, as much as possible, even if you feel well.

"If everyone respect these instructions, together we will avoid the propagation as much as possible and fight to avoid transmitting it to people, who may have aggravating symptoms.

"Many thanks for your support message, take care of yourself and your loved ones and respect the confinement instructions to avoid the spreading."

Mangala spent five years at City before moving to Valencia in 2019 and the Premier League giants tweeted: "Everyone at Manchester City wishes you a speedy recovery, Eliaquim".

There have been at least 7,800 coronavirus cases in Spain, with more than 290 deaths.

Globally, more than 6,400 people have succumbed to the virus from almost 170,000 cases.
