Actually PSG was wrong to sack Tuchel, it was proven that Tuchel managed to give Chelsea the Champions League trophy that PSG really wanted.
Owners really get restless when they are not getting the results they expect. They just want to change things up as quickly as possible instead of giving anyone a further chances. Its not PSG there are many clubs who just quickly go on firing as they get some loss streaks.
Now Tuchel will definitely try to win the Premier League trophy
He should win PL IMO given how he manages the team but don't know for sure as there are other capable teams in PL as well. Also there are underdogs which makes things difficult so its a very tough campaign. x
