Mendy underwent a meniscus operation after suffering a fresh injury setback in the 3-1 win against Manchester United in November.

He has had a full week of first-team training, with Pep Guardiola confirming: “”He’s in the squad, he will travel with us. Maybe he’ll be on the bench.
“I have a feeling he can give us something extra and hopefully in the last part of the season we can use him.
“He pushes from outside – he’s unstoppable. In the last third he’s so clever with his crosses.
“But in two seasons, he’s played very few and all the talks, training practice, he’s not there. He will need time to adjust to what we need with his quality.”
Kevin de Bruyne is set to start as Guardiola attempts to get the Belgian back full match fitness after two knee ligament injuries since the start of the season.
Phil Foden will also be in the starting XI, with Guardiola set to hand chances to a host of academy players.
Youngsters Ian Carlo Poveda, Iker Pozo, Taylor Richards and Felix Nmecha could all be involved.
Centre back Eric Garcia is likely to be handed another start, while back-up goalkeeper Aro Muric will also play.
Guardiola added: “Some players need rhythm and are going to play. The guys who’ve had a lot of games will rest. The ones who’ve not played too much or are back from injuries long-term are going to play.
“We start the game with 9-0 it’s unusual for a semi-final. The approach is to improve every single game, can help us to improve what we want to do.
“It would be nice (to win the trophy). It’s less important, but we respect it. It finishes in February and everyone forgets it.
“But we don’t think about what we are going to achieve. It’s one game, play, win, return next year and if we win we are in that position. We are close to being at Wembley and we want to win the title.”
