Bernardo Silva and Ilkay Gundogan are rumored to be leaving Manchester City soon. I know they have been important players in the Manchester City squad in recent seasons, so I think Manchester City will have a very hard time finding replacements for both of them if both players leave this season.
Gundogan has been linked with move to Barcelona, then Silva will go to PSG. If these reports are true, then of course Manchester City are in big trouble especially about finding the right replacement.
Manchester City is a team that has large enough finances so it won't be difficult if you want to find a replacement for these two players but if Manchester City still wants them to play then I'm sure there will be a more appropriate offer for them to keep playing for Manchester City.
In this season, Manchester City has shown that they have a very sharp attacking side and a strong defense so that several players will continue to be defended so that their game next season will not decrease.
