It will be a whole lot of tasks for Enzo because much will be expected from him to at least make Chelsea appear top 4 of the Premier League table and to win a trophy at the end of the season since he will coach Chelsea from the start of the season to its end, not coming to coach or take over the coaching job from the middle of the season as other sack coaches of Chelsea has done in the past.
It is the first season for Enzo, surely he has a lot of things to be done. Even if Mauricio Pochettino has built Chelsea squad well but it may not an ideal squad for Enzo. I heard that Chelsea is still expecting to sign some new players. It means they are still unsatisfied with the current squad with a lot of talented young players.
Last season, Chelsea finished in the top 6, it was not too bad achievement. Next season, Enzo should be expected to lead Chelsea to finish in the top 5 at least. If Chelsea can finish in the top 4, it will be a good achievement for Enzo. It won't be easy for Enzo to lead Chelsea to finish in UCL zone.
