The Manchester City boss has won it all since starting out as Barcelona's boss back in 2008 (including the treble in his first season in charge of the Catalan club) and is duly leading the Citizen's to a very stylish Premier League title this season.
Jesus, 20, sustained the injury during City's trip to Selhurst Park, where the runaway league leaders were held to a 1-1 draw against Crystal Palace on New Year's Eve.
The 24-year-old signed a five-year deal when he moved to the Etihad for a mammoth £35m transfer fee last June and has since become an integral part of Pep Guardiola's side, who boast a 16-point lead at the top of the Premier League.
"He has done one or two weeks training alone and today is the first training joining the team".
Guardiola added: "Being here, I feel English, I feel even more part of this league".
"I think the club made a statement and it was so clear what happened", Guardiola said.
He said: 'It would be good for my players not to think too much of the final next Sunday, they (should) think about the final next Monday.
"Of course, I am concerned because I saw Wigan's game against Bournemouth", Guardiola said in Friday's press conference. It's one game, the chance to go to the quarter-finals and we are going to prepare as much as we can'.
Wigan Athletic manager Paul Cook: "We've got a fantastic stadium and the support inside it will make it a really good atmosphere, that's a guarantee".
