I still think this massive overhaul is problematic even though it looks good, but of course with some new players and coaches, it will be like going back to the beginning and starting again and again every season if it continues.
Chelsea's play in terms of possession and initiation from the midfielders is good enough, now it's just a matter of focusing on how they don't waste opportunities.
On the other hand at the moment I don't want to defend Pochettino but we want something instant in the few matches Chelsea have had
I think It is evident that Chelsea has recently experienced significant difficulties, particularly as a result of the injuries to certain key players. Despite these difficulties they have done a great job of maintaining possession of the ball and attempting to score goals, which demonstrates their tenacity. Their coach Pochettino, must adjust to these issues and utilize the fresh players they have. Because of his seriousness as a coach, the team fundamental problems might be resolved. We must all exercise patience and have faith in Chelsea ability to bounce back even stronger. Pochettino commitment and expertise will undoubtedly aid the team in improving and Chelsea supporters should be optimistic about the future.
Btw Chelsea's problems aren't just recent as they've been going on all last season until now

It's just that for now we just need to wait for how Pochettino steps in with the strength he has now when their players recover from injury whether Pochettino will be able to improve Chelsea's performance or not in a better direction.
I still feel that there is no need for them to change significantly but only need to improve to be better than last season it is very good for Chelsea because to change significantly after a bad performance is difficult to happen but when they can be in a better position at the end of the season it is very good for them.
