Roberto Mancini's right-hand man has insisted the Premier League champions want to reach a point where they can cope with the absence of even their biggest stars
"We have to look at things," Platt told the Manchester Evening News. "We want to get to a point where nobody is indispensable.
Goal.com exclusively revealed on Monday that City is not planning on offering their Ivorian midfielder - who was signed from Barcelona two summers ago - a new contract next summer.
And Platt, who is Roberto Mancini’s right-hand man at the Etihad Stadium, wants the club to reach a stage where it isn't reliant on certain players to win matches and pick up points.
"What we know with Yaya, he can give us so much balance, so much control of the game – a lot goes through him," Platt explained.
He added, "With David, when you think you are coming up against a tight defense, he can open things up with his ability.
"We address every game as it comes, with one eye on what the players have done and what the players are going to have to do in the next game. A lot is made of people missing games but we don't just pick a team for one particular game."
