I'm not defending Pochettino, but look at Chelsea recent performance, they have improved and managed to reach 7th place in the standings, but the improvement in the remainder of this season is not really expected by Chelsea fans because it is too futile to try to get the best place.
I'm a little surprised why Chelsea can perform so well towards the end of the season, whereas at the start of the season their performance was very unstable and they almost gave up hope that they would experience a bad season in the next few years.
after seeing this change, Chelsea believes that Chelsea can still improve in the coming season if they can retain Pochettino, although there are no guarantees, but at the end of this season it looks convincing and it seems Pochettino already knows what he has to do.
currently looking for the best manager is not the best way because Chelsea has started to show positive changes and there is no harm in maintaining the existing ones and just trying to change some unproductive players to strengthen every line that needs to be improved.
Three matches left in Premier League and see how possibilities standings position finish in this season for Chelsea after success moving up from 10th to 7th standings awhile. Currently Chelsea has chance break out to 5th standings position depend their consistency performance or not in three matches left against Nottingham Forest, Brighton Albion and Bournemouth.
Pochettino improved well with team performance currently and I think bad viewed from fans currently will defend him keep becoming Chelsea manager for next season, I think if can reach UEFA Champion League spot place in this season will make good performance as first season become Chelsea manager and make many rotation with players composition.
