I see it totally normal that Mudryk didn't perform very impressively this season. Because the whole squad of Chelsea were very inadequate. Their morale was so low that they even gave up on the season quite early. In this situation it wouldn't be a healthy assessment about a player. There is a new period starting for Chelsea now with Pochettino. This is going to be the most important time period to watch Mudryk's capabilities. If the team make a good start the expectation from him will also be high.
If he still can't impress people then I will also agree with the people who think he isn't good enough for Chelsea.
Most persons will blame his poor form on the overall performance of the team but even in that situation some other players managed to make good impact for the team. I really hope he finds favor with the new boss who will be taking over from the next season, because if he doesn’t get playing time, how will he prove himself?
It is still possible but of course it also comes at a price different from Mudryk.
This season since he was bought, he still hasn't found his best form and of course it will be a little complicated if he continues like that so he has to try to improve again because the EPL is a tough match so when he is still monotonous like this season then this will be very hard for Mudryk to survive.
On the other hand, boosting the confidence of the coach is also important so Pochettino apart from having to improve the existing scheme, he must also try to increase the enthusiasm of the players because this is also very important for their continuity next season.
