I think it is unrealistic for Pochettino to help Chelsea get to the top of the league with just 2 months into the new job; new players and new signings too. Pochettino has alot of tasks and work to put Chelsea in place; determine a starting 11, develop the team rhythm and chemistry before even thinking about a title challenge.
Worst case scenario, i think Pochettino should be able to get Chelsea to fight for an Europa league position because even Champions league football is far fetched (atleast on paper).
It is extremely premature to draw the conclusion that Chelsea are going to start win games; we're yet the opportunity to witness them perform on the pitch, like Manchester United did yesterday. The players are eager to make their club debuts; nevertheless, we should take an additional look at the roster; I don't believe they are currently ready to play games. Mauricio Pochettino has quite a bit of work to complete at Stamford Bridge. He has the ability to either boost or degrade the club's performance, depending on the strategy that he implements.
It's true that it's too early to draw conclusions about what Chelsea will achieve next season because they seem to be a new club after the poor results last season, maybe Pochettino at Chelea will take a long time to repair the damage done there, but we can too see how some managers are able to change their club in a fairly short time, like Unai Emery at Aston Villa even after his presence Aston Villa went unbeaten in several matches and after previously struggling in the middle table he was able to bring Aston Villa to end up being ranked in the European zone, so it is not impossible for Pochettino to do the same with Chelsea so that Chelsea can play in European competition for the 2024-2025 season, moreover they will benefit enough because they only focus on domestic competition so they will not face a busy schedule.
