Overall it's hard to say for now, we'll see what happens in the new season, but at the moment my opinion on this player is the same, he hasn't proven anything yet. As Chelsea have had a good transfer window, we are in for a big change, I think a lot of people will be happy when Chelsea start to get back to the top
Yes, we still can't assess the performance of the new coach at this time because the season hasn't started yet. Previously, the old coaches also did a number of things to bring in their target players who were expected to be able to bring Chelsea to become a big club and be able to rise to the top rank. However, the results really did not match expectations, even this was very bad last season. They were able to get several players but they failed to optimize them.
now it's time for Pochettino to prove how skilled he is as a Chelsea coach, by starting to shop for a number of targeted players. then what are his tactics and strategies to optimize the performance of the players in his club. This is very hard homework for Pochettino, of course. And it's a challenge, how can he prove that he is a proper coach and a good fit for Chelsea.
