Wojciech Szczesny is in line to make his Barcelona debut against Alaves in La Liga on Sunday – just over a month since he had announced his retirement.

Former Poland international Szczesny, 34, announced that he was hanging up his gloves after his contract with Juventus was terminated, but has now reversed that decision after Barca lost first-choice goalkeeper Marc-Andre ter Stegen to a serious knee injury in their 5-1 win against Villarreal last month.

“He is not going for the money at Barcelona, I can tell you that much,” Spanish football expert Guillem Balague said on the Euro Leagues podcast.

“They needed something after the injury to Marc-Andre ter Stegen. I get the impression he is coming to be the number one and play in the big games, and have an experience that will run until next summer.”

Barca go into the game looking to bounce back from their 4-2 defeat by Osasuna, as reigning champions Real Madrid look to do the same after their 36-match unbeaten run in all competitions ended against Lille in the Champions League on Wednesday.

Carlo Ancelotti’s side play Villarreal at the Bernabeu and trail Hansi Flick’s Barca side by three points.

“Defeat is an opportunity, if we take it and react well,” Ancelotti said.

“We are self-critical. There are times when you have to reconnect and you need to do it quickly.

“Sometimes a good run makes you think you’re invincible, but a defeat brings you back to reality. We are still not at our level, we have players who are not at their best.

Kylian Mbappe returned as a substitute at Lille after a thigh injury and the France striker may start this weekend, with Andriy Lunin set to deputise in goal again for the injured Thibaut Courtois.

Girona and Atletico Madrid also suffered Champions League defeats on Wednesday and both are in action on Sunday, against Athletic Bilbao and Real Sociedad respectively.
