Mumbai Indians are favourites to claim a historic third successive Indian Premier League crown back on home soil.

The Indians retained their title in Dubai last year with a victory over Delhi Capitals, taking their record tally of IPL triumphs to a five.

Rohit Sharma's side will be the team to beat in a competition that will be played in Ahmedabad, Bengaluru, Chennai, Delhi, Mumbai and Kolkata, having been staged overseas in 2020 due to the coronavirus pandemic.

The Capitals and Royal Challengers Bangalore look the most likely sides to prevent Mumbai from becoming the first franchise to win three consecutive IPL titles.

We pick out some of the things to look out for in what promises to be a mouthwatering extravaganza of cricket, which starts on Friday in a country that will stage the T20 World Cup later this year.

INDIANS PRIMED FOR THREE IN A ROW

The champions start the defence of their title with a blockbuster showdown against RCB in the first game of the tournament at M. A. Chidambaram Stadium in Chennai.

Mumbai will have to wait for Quinton de Kock's arrival as he is on duty with South Africa, so skipper Rohit will be expected to set the tone at the top of the order.

The India opener is the fourth-highest run-scorer in IPL history with 5,230 at an average of 31.31 and, although the 2020 edition was not one of his best, he struck a rapid 68 in the final. Ishan Kishan and Suryakumar Yadav played significant hands with the bat in Mumbai's 2020 success.

Trent Boult was man of the match in that win over Delhi after taking 3-30 and the New Zealand seamer will have a big part to play with the ball along with Jasprit Bumrah.

STAND-IN SKIPPER PANT CAN LEAD BY EXAMPLE

Delhi's first IPL final proved to be painful in November, but they will fancy their chances of going one better under the captaincy of Rishabh Pant.

The addition of Steve Smith, who was released by Rajasthan Royals, is a major tonic, while Umesh Yadav and Sam Billings are among their other new recruits.

Kagiso Rabada was the leading wicket-taker in last year's tournament with 30 at 18.26 and Delhi will need him to fire again along with fellow Proteas quick Anrich Nortje.

Ravichandran Ashwin should be on a high from his Test exploits for India against England, while the in-form Pant can thrive as skipper with Shreyas Iyer ruled out due to a shoulder injury.

MORRIS UNDER PRESSURE TO JUSTIFY PRICE TAG

Chris Morris became the most expensive signing in IPL history when he was snapped up by Rajasthan Royals for 16.25crore (around £1.6million).

That staggering fee put the South Africa all-rounder ahead of Yuvraj Singh (16cr) as the biggest ever auction acquisition.

Morris was 20th on the list of the leading wicket-takers last year when featuring for RCB and only batted five times, with a top score of 25 not out.

ROY TO REUNITE WITH BAIRSTOW

England batsman Roy went unsold at auction but was drafted in by Sunrisers Hyderabad last week after Mitchell Marsh withdrew for personal reasons.

Sunrisers coach Trevor Bayliss was clearly excited by the prospect of Roy and Jonny Bairstow forming a pairing that has served England so well.

Roy may have to wait for his opportunity or Sunrisers could tinker with the order, as captain David Warner and Bairstow have formed a dangerous opening pairing.

England paceman Jofra Archer has been ruled out of the ODI series against India due to a worsening elbow injury.

After a 3-1 Test series defeat and a 3-2 setback in their T20I clashes with India, world champions England will look to end their tour on a high in three ODIs to be played in Pune over the next week.

Archer will be flying back home for checks on his injury, however, and the England and Wales Cricket Board (ECB) said he must also miss the start of the Indian Premier League (IPL).

That deals a blow to Rajasthan Royals ahead of the tournament that begins on April 9, with Archer having impressed against India in the T20 games.

The ECB said on Sunday: "Jofra Archer is returning to the UK for further management and investigation of his right elbow injury.

"Archer's elbow issue has deteriorated over the course of the Twenty20 International series and made it increasingly challenging for him to maintain performance levels. He has been deemed unfit for selection for the ODI series that features matches on 23, 26 and 28 March.

"The ECB medical team will assess the player and, together with Jofra, develop a treatment plan and a return-to-play schedule in due course. As a consequence, Jofra will miss the start of this year’s Indian Premier League."

England's ODI squad, aside from the obvious loss of Archer, is comprised of players selected for the T20 series and the reserves for those games.

England squad: Eoin Morgan (captain), Moeen Ali, Jonny Bairstow, Sam Billings, Jos Buttler, Sam Curran, Tom Curran, Liam Livingstone, Matt Parkinson, Adil Rashid, Jason Roy, Ben Stokes, Reece Topley, Mark Wood.

Also travelling with the squad: Jake Ball, Chris Jordan, Dawid Malan.

Chris Morris became the most expensive signing in the history of the Indian Premier League as franchises filled out their rosters during Thursday's auction in Chennai. 

Morris was eventually signed by Rajasthan Royals - who he played for in 2015 - following a bidding war that saw four teams battling it out to secure the services of the South African all-rounder. 

His final price finished up at 16.25crore, which equates to around £1.6million, putting him ahead of Yuvraj Singh (16cr) on the list of biggest auction purchases in the global Twenty20 tournament.

"I'm super-stoked, super-humbled to be joining Rajasthan again," Morris said in a video message posted by his new team on Twitter.

"I had an unbelievably good time, and a good season, one of the better times in my cricket career, with Rajasthan in 2015, so I'm unbelievably happy, unbelievably excited.

"We have a very good squad, so joining up with Rajasthan is a very cool experience."

Royal Challengers Bangalore were big spenders in their bid to secure a maiden title this year, getting New Zealand paceman Kyle Jamieson for 14.25cr (£1.5m) having already signed Australia all-rounder Glenn Maxwell (14cr - £1.4m) for a fraction less than that earlier in proceedings. 

Jhye Richardson also collected a huge deal, snapped up for the same price as compatriot Maxwell by Punjab Kings, who added another Australian paceman to their roster in Riley Meredith, who has yet to play international cricket in any format. 

Having been released by Rajasthan Royals at the start of this year, Steve Smith is now a member of the Delhi Capitals, along with India fast bowler Umesh Yadav and Englishman Sam Billings. 

Moeen Ali saw a considerable rise from his base price, the England all-rounder eventually going for a final sum of £700,000 to Chennai Super Kings. 

While a premium was paid for pace bowling during the auction, the market was a little less frantic for batsmen. 

Dawid Malan – who sits top of the International Cricket Council's batting rankings in the shortest format – will play for Punjab Kings, but English openers Alex Hales and Jason Roy both went unsold. 

Bangladesh all-rounder Shakib Al Hasan is heading back to the Kolkata Knight Riders for 3.2crore (£315,000), while Krishnappa Gowtham went for 9.25crore (£900,000) to the Super Kings, making him the most expensive uncapped India player ever.

As for Mumbai Indians, the main additions by the two-time defending champions came to their bowling attack as they added Adam Milne, Nathan Coulter-Nile and leg-spinner Piyush Chawla. 

The 14th edition of the IPL is scheduled to begin during April and run into May. Last year's delayed tournament was staged in the United Arab Emirates due to the coronavirus pandemic.
