Manchester City manager Pep Guardiola has vowed to "rescale absolutely everything" during the next two transfer windows by giving unhappy players a chance to move on.
The unbeaten Citizens are looking good value to earn a third Premier League crown this term after moving well clear at the top of the division, while continental success is also a realistic target.
Looking further ahead, however, Guardiola is not ruling out another busy period of transfer activity, having already completely overhauled his full-back department earlier this year.
Asked specifically about the future of Eliaquim Mangala, who has yet to start a league game under Guardiola, the Catalan told reporters: "He is our player and he is going to stay here. In the future, in the winter break and in the summertime we are going to rescale absolutely everything.
"Not just with Mangala, for everybody. The club is going to ask them if they are happy or if they are not; if they are comfortable in the position they had in the past, playing or not playing? They have to decide. The future will be like this. We always want players who want to stay here.
"But Mangala is a player with a lot of experience who played at a high level in Porto, last season in Valencia, now here and with the national team in France. I am really impressed about his behaviour in the training sessions. He hasn't played regularly until now and he has always accepted it.
"When that happened he kept his head down. For a manager, for a club and for the environment in the squad that is so important. Of course he has his specific qualities. In the Premier League that is important sometimes. So we are going to use him when we believe we need him."
Midfield pair Yaya Toure and Fernandinho are the only two City players due to be out of contract at the end of 2017-18.
