If Pep Guardiola wants to leave Manchester city his next destination will be PSG since he loves going to clubs that have the money and are willing to spend. Pep Guardiola with PSG will win them the champions league very easily. With just few signings, Pep Guardiola can make PSG into a team like Manchester city but Pep Guardiola won't be leaving city just yet. He'll try to win more trophies with Manchester city and defend their champion league trophy. If Pep Guardiola was to leave Manchester city at this very moment, everything they have built in the past years will crumble.
But not only does PSG has money Newcastle to has money but I don't think Pep will want to move from manchester city any time soon, he still has plenty of surprises to give to the city and I feel his very much comfortable there, we should hold our horses don't be surprised if pep goes to psg the club will improve, but not certain about winning the champions league even last season the people I had in mind was Madrid because I was sure that inter milan will not win, and watching the final manchester city did not even struggle to win the champions league.
Guardiola may not be planning to leave Manchester City at the moment as there is no reason for him to leave the club at the moment. PSG will improve if Guardiwala goes to PSG but recently former Barcelona manager Luis Enrique took over as PSG manager. Luis Enrique is an experienced and tactical enough manager that PSG will improve under him. Luis Enrique has already joined the PSG training camp. There is no chance of Guardiwala going to PSG at the moment as Luis Enrique has taken over as PSG manager.
A good manager does not take responsibility for any team that he can improve with. Good managers agree to work with that team.
