Haaland is the best player that Manchester City currently has. Of course the club will not sell its star players very easily because Haaland is a player who really suits the club playing style and since Haaland arrival at Manchester City he has immediately shown his talent and has scored a lot. goal for Manchester City.
It seems like Haaland feels comfortable at Manchester City and Haaland will really develop his career at the club and it is possible that Manchester City will continue to extend his contract, but if Manchester City can find a truly suitable replacement, of course Manchester City will sell Haaland at a very high cost, of course to recruit other better players so that they can maintain their performance from year to years.
Yes, Erling Haaland has become a future asset for Manchester City and I am sure Manchester City will not just let the plyers they currently have leave. He is still young, and with his outstanding performances for Mnchester City he will certainly continue to try to be retained. We all know that Manchester City are in very good shape now, and they are solid. Haaland has been a goal-scoring machine for them. I don't see him being sold anytime soon.
I mean why would Mbappe want to stay here any longer? PSG are still struggling too much as you have seen until now. They might even be under the danger of dropping to the Europa League after the group stage. Because that performance against Newcastle was horrible and they would experience that also if they continue playing similarly.
Mbappe has of course been given a lot of money by PSG to extend his contract. However I don't think the same thing would be enough to convince him now.
Because for example Real Madrid are also very rich and Mbappe can simply choose them and continue to make a lot of money.
There is no reason for Mbappe to stay longer at Paris Saint Germain, unless he wants to make Paris Saint Germain even better. But what I see now is that he also doesn't feel at home here for long. And I'm sure next season he will join a new club, and there will definitely be a very long drama between him and his current club.
He refused a contract extension this season, but Paris Saint Germain could convince him. I heard there was a special agreement that he changed his mind to extend the contract.
