Honestly speaking, Mudryk is not that bad, I believe he's just a player who hasn't gotten that playing time. With him being on the bench always how do you expect him to perform or even get a goal and assist. A different era has come and it will affect the players on the Chelsea squad positively, Pochettino is going to turn things around for the blues.
 So I can't say Mudryk is a bad player because Pochettino will make good use of him and he can be one of the deadliest player in the EPL next season.
