Joao Felix’s overhead kick sealed Barcelona a 1-0 win at lowly Cadiz and lifted his side back to within eight points of LaLiga leaders Real Madrid.

The Portugal forward converted with a bicycle kick following a first-half corner and with the help of two crucial saves from goalkeeper Marc-Andre ter Stegen, Barca extended their winning run in all competitions to six matches.

Barca, who edged the first leg of their Champions League quarter-final 3-2 against Paris St Germain in midweek, are now unbeaten in 13 before next weekend’s El Clasico at the Estadi Olimpic Lluis Companys.

Cadiz had boosted their survival hopes by winning two of their previous three in LaLiga and they had their chances, but they remain three points from safety.

Felix’s strike lit-up a first half of few clear-cut chances, in which Cadiz went close to taking a 22nd-minute lead when Javi Hernandez’s drilled angled effort forced Ter Stegen into a sharp near-post save.

But Barca edged in front in the 37th minute with their first real effort on goal following a corner.

Sergi Roberto headed the ball on and Joao Felix swivelled to send a bicycle kick inside Cadiz goalkeeper Conan Ledesma’s right-hand post for his sixth league goal of the season.

Barca should have extended their lead shortly before half-time when the ball broke to Fermin Lopez on the right edge of the box, but his goalbound shot was brilliantly blocked on the line by Cadiz defender Victor Chust.

Cadiz thought they had made an ideal start to the second period as Juanmi turned home Iza Carcelen’s low ball into the box, but the effort was ruled out as the striker was clearly offside.

Chust then headed narrowly wide for the home side, whose appeals for a penalty soon after when the ball appeared to hit Barca defender Pau Cubarsi on the arm were waved away, with the incident not reviewed by VAR.

Felix went close to doubling Barca’s lead through his first-time effort from Ferran Torres’ cross as the action flowed.

Barca were indebted to Ter Stegen with 10 minutes remaining as the German goalkeeper’s flying save from Diadie Samassekou’s thumping long-range shot preserved their slender lead.

Following Real’s 1-0 win at Mallorca earlier on Saturday, Barca closed the gap back to eight points ahead of next Sunday’s showdown between LaLiga’s top two.

Barcelona have been dealt a double injury blow with the Catalans revealing that Alejandro Balde will undergo hamstring surgery in Finland.

Fellow defender Sergio Roberto is also set for a spell on the sidelines with an Achilles problem.

“Tests show that first-team player Alejandro Balde has an injury to the tendon in his right hamstring,” Barcelona said on X, formerly Twitter.

“In the coming days he will undergo a surgical procedure at the hands of Dr Lasse Lempainen, under the supervision of the club’s medical staff, in Turku, Finland.

“Once the procedure has been carried out a new statement will be released.”

On their club captain, who has had an injury-hit season, Barcelona said: “First-team player Sergi Roberto has a problem in his left Achilles tendon.

“The player is unavailable for selection and his recovery will dictate his return.”

Barcelona return to LaLiga action against Villarreal on Saturday seeking to bounce back from their midweek Copa del Rey defeat at Athletic Bilbao.

They have won their last three league games and beat Villarreal 4-3 away in August.

Sergi Roberto came to Barcelona’s rescue with a brace to finally see off rock-bottom Almeria 3-2 as the LaLiga champions returned to winning ways.

The hosts looked set to stretch their winless run to four games in all competitions after twice being pegged back by opponents still in search of their first league win of the season.

But the 31-year-old latched on to a through-ball from Robert Lewandowski in the 83rd minute to grab the points which take his side back within four points of second-placed Real Madrid.

Xavi’s men were overwhelming favourites as they aimed to shrug off their recent poor run, and they started on top.

Joao Felix floated a free-kick just over the crossbar then Sergi Roberto saw his first chance well saved by busy Almeria goalkeeper Luis Maximiano.

Joao Cancelo was next up with an effort that he drilled straight at the keeper, before Fermin Lopez headed over from Ilkay Gundogan’s pinpoint cross.

Sergi Roberto blasted over from long-range on the half-hour mark before Barca finally made their seemingly inevitable breakthrough three minutes later when Ronald Araujo’s deflected effort fell to Raphinha who fired it into an empty net.

Lewandowski almost doubled Barcelona’s lead before Almeria snatched their chance to level four minutes before the break, Leo Baptistao lofting the ball over advancing Barca keeper Inaki Pena and surviving a VAR check.

Baptistao had a chance to put his side in front before the break but dragged an effort wide and normal service resumed early in the second period with substitute Ferran Torres and Lewandowski both denied.

Sergi Roberto grabbed his opener on the hour when he met Raphinha’s corner with a header at the near post to put Barcelona back in front.

But the lead lasted barely 10 minutes before the hosts were undone by a calamitous error by Pena, who dropped the ball in a collision with Araujo, allowing the alert Edgar Gonzalez to slide it into an empty net.

The hosts responded well, Araujo making up for his part in the equaliser by heading just wide, before Gundogan contrived to somehow miss his chance with the goal at his mercy.

Sergi Roberto finally grabbed what proved to be the decider in the 83rd minute when he ran on to Lewandowski’s ball through the middle to seal three hard-earned points.

Lewandowski almost added a fourth and the captain was denied a hat-trick deep into added time when his effort rattled back off the woodwork.

Xavi has urged Barcelona to “recover our ideology” before beginning a critical week of their season.

Barcelona have three home games in the space of six days, starting against Athletic Bilbao in LaLiga on Sunday.

Shakhtar Donetsk provide Champions League opposition on Wednesday and Real Madrid make the trip to the Nou Camp next Saturday for the first El Clasico of the season.

As LaLiga returns following the international break, leaders Real held a three-point advantage over Barcelona.

“At the start of the season, we’ve had some great moments of playing well,” said Xavi, whose side have dropped points in two of their last three league games with 2-2 draws against Mallorca and Granada.

“We must recover our ideology and get the three points by playing well.

“We are in a situation with a lot of absentees, but it won’t be an excuse for the game and to be able to play well.”

Alejandro Balde and Lamine Yamal have both been declared fit for the Bilbao clash.

But Frenkie de Jong, Jules Kounde, Pedri, Raphinha, Robert Lewandowski and Sergi Roberto remain unavailable.

Lewandowski, Barca’s top scorer with six this season, is closing in on a return after ankle trouble and Xavi said the Poland forward “has a very good feeling” of returning against Real Madrid.

Xavi said: “He’s a great leader and always goes forward, he wants to be there and he’s hurting less and less every day.

“He has a very good feeling. He always pulls himself forward.

“But there is a lot of variety (in attack) and people with confidence in front of goal. That is great. Last year, we depended a lot on Lewandowski.”

On the potential return of other individuals, Xavi added: “The player’s feelings will tell when he will arrive. We won’t force anyone.

“Feelings are the key and they will mark the return of all of them.”

Bilbao began the weekend in fifth place, four points behind Barcelona after beating Almeria 3-0 before the international break.

The Basques side are managed by Ernesto Valverde, who won two LaLa titles and a Copa Del Rey during his time in charge of Barcelona between May 2017 and January 2020.

Xavi said: “Athletic are very strong physically and technically gifted. Valverde is a great coach and likes to press high.

“I’m expecting a difficult opponent, we have some injuries but that’s no excuse and we need our fans.

“We’re three points behind the leaders. But we have to keep working hard, to keep fighting, and to keep improving, because there is a long way to go in LaLiga.”

Barcelona midfielder Sergi Roberto is set for a spell on the sidelines with a calf injury.

No time frame has been put on the 31-year-old’s recovery as the LaLiga outfit’s injury problems continue to mount up.

Barca boss Xavi has been without injured players Jules Kounde, Pedri, Frenkie de Jong, Raphinha and Robert Lewandowski since before the international break.

A statement from the club’s official website read: “First-team player Sergi Roberto has a soleus muscle injury in his right leg and will be unable to play until the problem goes away.”

However, Spain internationals Alejandro Balde and Lamine Yamal returned to training on Wednesday following their recent issues.

Balde sustained an adductor injury while on international duty that forced him to miss Spain’s victory in Norway which clinched qualification for Euro 2024, while 16-year-old Yamal – Spain and Barcelona’s youngest ever goalscorer – has recovered from a hip flexor problem that ruled him out of selection.
