Moreover Chelsea interest in this player is quite high, they are trying to bring in young players in their squad, it seems that this would be a good choice for Julian Alvarez so that he can develop himself and also get more playing opportunities, because his current performance is in good condition so it is very unfortunate if you don't get a position on the team.
If Alvarez chooses to leave Man City, this will be a very good choice for him to develop his performance because at a young age like him, he will work optimally if he plays.
A young player like Julian Alvarez will definitely still be looked at by many teams at this time if he can really leave Manchester City. Because currently there are many teams who are targeting young players whose talents can still be developed by all coaches because this will also be the most important part for any team. But Manchester City itself will not just let go of a young player like Julian Alvarez at such a cheap price if Manchester City really wants to sell Julian Alvarez at this time. So the team that is eyeing this player must also consider a suitable offer for this young player.
Young players are now like prima donnas for big teams, because with young players they can make their future brighter and currently Julian Alvarez is one of the players who is being looked at by many big teams, one of which is Paris Saint Germain.
However, as you said, it will be very difficult to get Manchester City to let go of their players, especially since I also heard statements from Manchester City that they are not interested in letting go of Julian Alvarez. That makes the chances of the team wanting him even smaller with what Manchester City said.
I also haven't heard that Julian Alvarez wants to leave Manchester City and maybe he still wants to stay with this team. Moreover, Pep Guardiola also seems to still need this player to remain in the squad.
