IMO in this case I think as long as there is no proof then indeed we cannot give any reference to Pochettino.
We know that at first when talking about Potter, also with a series of slick performances at Brighton, many people gave Potter a lot of hope when replacing Tuchel, but this created expectations that were too high which made them have to be willing to fall quite hard.
At the moment Pochettino does see from experience that he is quite familiar with how the Premier League is run and of course even though he only won domestic titles at PSG this is also an achievement for him but in other matters of course we also have to reflect on what was before. The hope is that he can improve Chelsea's performance which has been destroyed this season but of course a heavy burden will also be carried and hopefully he can give his best according to the expectations given at this time.
You are right, high expectations sometimes bring disappointment at least that's what happened to Chelsea last season even though they have everything they need, including European top players and fresh funds. Some people argue that Graham Potter cannot implement the right strategy but we don't know what the real reason, what is clear is that at this time Mauricio Pochettino needs more effort to bring Chelsea to the best places especially next season the competition for the Top 4 is getting fierce because the Premier League has a newcomer like Newcastle which has been proven to have taken place at the 4th place
.
And the main problem that's happened to Chelsea I think is because Chelsea have been under three different coaches and also there have been mid-season squad changes throughout the season so the balance of the team has been shattered and it's been inconsistent for Chelsea. Due to differences in coaches that have an impact on changes in strategy and also changes in players.
and Chelsea really have to have the right coach so that there are no more changes in coaches, and I hope Mauricio Pochettino can turn Chelsea into a team that can compete at the top. Because next season the competition will be much stronger and tighter because several teams made significant changes last season and of course next season will be much better and stronger, and Chelsea must be able to be better than them especially with Newcastle which I think next season he will be one of a team not to be taken lightly.
