The work of the last two managers at Chelsea has really made the job of rebuilding and making Chelsea a very competitive club once more to be a very big task. It was started by how clueless Graham Potter was with his style and ultimately ended with Frank Lampard's gambling style of of football.
However I have a strong opinion that Mauricio Pochettino will definitely make everything work again at Chelsea. He has the potentials to turn the club's fortunes around I believe he'll definitely do a good job at Chelsea come next season and beyond
Pochettino's task next season to make and change the Chelsea team for the better will not be easy even though some people may believe that Pochettino has the ability to make Chelsea better. Because apart from the players who have to follow Pochettino's own direction and style, the team must also provide better players for Chelsea so that there will be more significant improvements for Chelsea next season through their new coach.
Whether or not Pochettino will succeed with Chelsea remains to be seen. But I would say don't get your hopes up too much. Maybe coach Pochettino can stabilize the Chelsea team. But qualifying for the Champions League will also be difficult for Chelsea. Pochettino has been with PSG for a long time. A lot of star players were in PSG's squad. Even then Pochettino was not successful with PSG. PSG's performance was unstable. And so I would say Chelsea fans should not expect too much from coach Pochettino.
