Saying Manchester City are threatened to lose a great coach like Guardiola is unfair, when they signed him did they expect to have him forever? No that is impossible. Signing a coach or player means you get to enjoy their services for a certain period of time unless they choose to stay longer. Guardiola have tried so much for the club, he has taken them to heights they didn’t imagine and have won lots of trophies for them and if he thinks he want to end it then they should respect his decision because he would not stay forever. If he was to stay forever in a club it would have been Barcelona but he left after a few years.
It best for them to look for replacements as soon as possible. Xabi Alonso has the potential to manage Manchester City but they need to reduce their expectations of being like Guardiola, he is talented but still young in the managerial role so it could take him time to adapt to the premier league. I think is a good call for the team if Guardiola eventually leaves.
Guardiola definitely is one of the best, and I do wonder what he has in his mind to do next, many people are saying that he may consider a national team position, but Spain is doing great so far and England just hired Tuchel so I am not sure where he will go.
Plus, I wouldn't want a talent like Guardiola to be wasted at a national team, national teams play only a few games each season, which isn't nearly fun and that means we are going to miss him at some club that will play 50+ games a year. He already did amazing stuff at la liga, and he did amazing stuff at premier league as well, he didn't do much at bundesliga but he was there and won it too, the only thing left right now would be serie A and Ligue 1 as far as I know.
Would he consider some top team at serie a, like maybe Milan isn't looking great so he may go there? Not going to have too much financial help this time, or would he prefer to go to PSG where he would have the reigns and a ton of money to play with as well. I am not sure where he will go next, but as long as it's a decent club team I am fine with it, because national teams would be like a semi-retirement for a person like him, he doesn't deserve to be there, he deserves more.
