I wonder how many top players will decide to remain in Chelsea next season. Most of them came to the club with the expectation that they will be playing in the champions league and some of them came from top clubs. Chelsea have started their next season plan on a good note by bringing in an experienced coach but the have to be patient with him. His target shouldn't be to win any competition but to be in the top four positions. The disorganization in the Chelsea team will take a long time to reorganize. And Pochettino will be able to do the job.
I think the players who just joined in January will be staying at the club except for some who might not find favour with the new boss and some players who were already tipped to be sold in the summer, despite the expectations of most of the new arrivals to play in the Champions league I believe they still understand that Chelsea is a big club and getting back to playing in the Champions league will only take a short while, probably next season Chelsea will be able to finish in top four.
