Pochettino has a long experience in his coaching career so it's only natural that fans have high hopes for him to turn Chelsea into a stronger team next season. Previously, Pochettino was also successful with PSG because he managed to bring PSG to win the Ligue 1 trophy, even though he was later fired by PSG management, but he was a great coach in building a team.
Apart from that, Chelsea, which is inhabited by many players who have good quality, will of course be a strong support for Pochettino for next season. We need to see how Chelsea play under Pochettino where the first match will probably be in the friendly against Wrexham next month.
To be honest, I don't consider Pochettino to succeed when handling PSG, because they don't have strong competitors there I mean PSG is too great for Ligue 1, the situation will be different if he is in the Premier League who has more competitors. Indeed, based on experience and quality Pochettino is still reliable it's just that we have to wait for what steps taken at the start of the season so far I have not seen the big plan except to release several Chelsea players, yeah they still have time before the transfer window is closed.
but to be honest I doubt that Pochettino can make a difference to Chelsea because Chelsea's bad luck last winter was in the Chelsea players themselves who lacked consistency and performed too badly. and on the other hand, how many times has Chelsea fired coaches and changed coaches several times but everything was just in vain.
if in the summer Chelsea is still performing badly, it means that Chelsea needs a firm coach.
