Yes look funny, I'm not sure ManCity leave him for Serie A even not got the trophy for this year. Pep is the soul right now, it is the same as Barcelona before. He has much work to do for the future who haven't do. Haaland is his new project which has not been done, he is still a long investment, and he has an obsession to triple the price and after it happened he will left.
Erling Haaland is a very valuable asset for Manchester City, he can be said to be the next legendary player like Ronaldo and Messi, this is luck that comes directly to Manchester City because they get a player who has the potential to bring them to victory in this league and it seems Erling Haaland will not move to another club even though the price is higher because he really loves Manchester City.
In the near future maybe not. most likely he will stay at Manchester City, maybe he will try another club after undergoing 2-3 seasons with The Citizens. he is a phenomenal talent, his career in football seems to be getting brighter as he gets older.
On the other hand, Pep Guardiola's contract as a coach at Man City will soon expire.
The 2022-2023 season is the final year in which Pep Guardiola will lead the citizens squad, and so far there are no signs of an extension. however, if you look at the current strength of The Citizens. it seems a shame, if Pep Guardiola will end his contract with Man City.
some rumors say, Erling Haaland is believed to be a factor Pep Guardiola will stay at Man City.
