Pochettino already has the experience of coaching Premier League teams, but with Chelsea's current condition, of course, it makes Pochettino a little difficult and it takes a little time for him to improve Chelsea's performance again, the Chelsea team must be ready to process if they want to get up, not like what they did in the last season when sacking and changing many coaches.
Chelsea will certainly be ready to proceed with their new coach next season, because Chelsea and Pochettino know that the team was not in good condition last season. So there is no other choice but to go through a process to be able to improve their performance next season with the direction of their new coach and I'm sure Chelsea will be able to improve slowly.
With Pochettino having agreed to become the new Chelsea coach, I think he knows what's going on with this club and maybe he's ready to work out some of the best plans for this struggling club. Even though it is basically difficult to return to the previous Chelsea form and it is very possible for him to spend a lot of time in this job.
It makes sense what you say, because Pochettino certainly knows that the team he is coaching is a team that has fallen and needs to revive in a way that he will apply next season to Chelsea. Apart from that, Chelsea also needs to focus on the transfer market to get some of the best players so that the team can return to its true form with Pochettino's orders.
