Speaking to Slingo, Gallas said: "Chelsea fans donât need to worry about Cole Palmer this summer, he wants to see if he can win trophies with Chelsea. He would only leave if he thought it was the right time and that wonât be this summer.
"Cole Palmerâs performances have dropped when you look at what he was doing last season and even at the start of this season compared to now. I think he needs a rest. Thatâs why you have a big squad, so you can give your players a rest when they have so many games to play.
"Itâs been very intense for Cole Palmer and I think he could benefit from being on the bench for a game, he has to be managed well by Enzo Maresca. Palmer might benefit by coming off the bench in a game and having an impact in the last 20 minutes, he looks tired and he needs to be managed."
