Many times a great player proves his greatness with his absense. That's how people realize how crusial his role in his team. one of them is Kevin de Bruyne, his absence due to injury has been felt by the team in the past. His skillset and leadership on the field make him an invaluable asset to the club, and it's understandable that Manchester City would prioritize retaining him for the foreseeable future.
De Bruyne will continue to be a pivotal player for Manchester City in the foreseeable future. His contractual obligations and his integral role within the team make it improbable that he would seek a move elsewhere without substantial reasoning. Therefore, unless there are significant developments or statements indicating otherwise, it's safe to expect De Bruyne to remain a cornerstone of Manchester City's squad in the coming seasons.
De Bruyne always showed his important role for Man City. When he was absent because of the injury problem, Man City was difficult to score goals. Moreover, Haaland also got injured, Man City was very struggling to win the match. Now, when these players have recovered, they could make Man City stronger again. In the latest match against Luton Town, the role of these players was very clearly seen. Haaland scored 5 goals, meanwhile De Bruyne gave 4 assists. With this condition, I'm very sure that there is no way for Man City to sell these players.
De Bruyne is the master mind of Man City attacking, he organizes the attacking plan. He creates the opportunities for Haaland to score goals, gives him many key assists. So, he could score as many as possible. As far as I know, there is no other player in Man City squad who has the same capability as De Bruyne. It doesn't make sense if this key player to be sold in the next transfer window. I'm very sure the chance for De Bruyne to leave is under 50%.
