There is a possibility that after Chelsea have Pochettino can get a chance at least to improve performance to reach the top 5 in the premier league next season.
Maybe it seems impossible that the Chelsea players can improve with just a new coach but we don't know what will happen next and I think it's not only the coach who needs to be replaced but some of the attackers and defenders.
Even with Pochettino, their won't be any improvement in Chelsea's squad, Chelsea changed three coaches before last season ended and their was no any changes in their performance, the team was just getting worst whenever they signed a new coach, we all know that the last coach Chelsea had which is lampard is not really a experienced coach, but right now coach is not the only problem Chelsea is having. Chelsea needs to swipe out most of the players in their squad before their will be improvement in their team, most of those players are not really ready to play for the club, Chelsea needs young and talented players to bring them back to form, but if Chelsea wants to maintain their squad, then nothing good is going to come out.
