Manchester City Manager Manuel Pellegrini addressed Manchester City's continued lengthy injury list on Friday"
"Sagna worked today after ten days out, Mangala is injured - Nasri, De Bruyne and Bony are also out," he told journalists at City Football Academy.
"Bony has started working on the pitch these last two days. He needs at least one week more.
"Tomorrow we have a squad list - I have to talk to the doctor and the players who've recovered."
Regarding the injuries and its impact on squad selection for Chelsea on Sunday:
"We have just 13 players available to play - we have to play Champions League on Wednesday - we'll see the best team we can play on Sunday.
"We couldn't play on the Saturday for some reason, so we put out the best team we can.
"Young players have the option and they must take their chances. We normally have some young players in the cup - one or two maximum. I hope with the team we play against Chelsea, we hope they make the performance that we know they can.""Something must change because the Capital One maybe is a cup for the first part of the season and you always play Wednesdays, it's no problem.
"The FA is more difficult - you must start postponing games to get there as it's at weekends.
"Something is not correct with the cup - if you continue the final, you have to postpone three Premier League games and then fit them in later.
"You don't have time to play those games if you continue in Europe too.
"We always try to play with a strong team in every competition as they are all important - especially the FA Cup. We had two difficult draws against Premier League teams away and won 3-0 and 4-0.
"It's not so difficult to change one day of one game - if they can do it in other leagues, they can do it here."
