Pochettino the new Chelsea coach is not starting afresh or starting from worst. If you discover last season that Chelsea was struggling with form and losing all their matches. They were also signing good players. So it is correct to say that Chelsea has good players that they have signed, but the problem was that there was no chemistry between the players and the Coach and management. So it is now the function of Poch to put everything together to give Chelsea a successful season. The rebuilding started last season not this season.
Restructuring is basically what Chelsea needs at the moment, they will add more players to their previous squad. I have the feeling that the new management will outperform the prior ones. Todd Boehly may get this signing right, but he has a track record of committing mistakes. Mauricio Pochettino will fix Chelsea, but we shouldn't expect him to do it excellently in his first game. Fans and the board should be patient with Pochettino in case he fails to make an early impression. Chelsea is an exceptional club that requires complete focus from the board, the coach, the players, and the fans.
