Manchester City boss Pep Guardiola says only "small clubs" worry about selling players to direct rivals.
City go to Chelsea tonight with former players Raheem Sterling and Cole Palmer now with the Blues.
Guardiola said, From my point of view, I give my opinion to the club but after that the club has to decide if the transfer is good for both sides and for the player.
But never ever (has it been an issue). I think that means you are a small club. Big clubs make decisions for the benefit for all three parties: players, both clubs and agents sometimes. Really, it's not a problem.
So if they want to go to Chelsea or (Manchester) United or, I don't know, Liverpool or whatever, what is the problem? They are happy to be there, the club is happy for the transfer.
Another player would come and we'd keep going: good spirit, good mood, and try to do it."
