From the start of next season to its end, I don't expect Enzo to have magic done in the Chelsea team. We will be seeing the same results, no difference in the team will be made at this time, if Chelsea likes let them sign young talented players to their squad. The impact will not be felt in the team unless Boyle begins to learn how to be patient with Chelsea's coach rather than be in a hurry to sack them. The sack of Pochettino was a mistake move taken, I believe he won't repeat the same mistake with Enzo, to sack him without coaching Chelsea to the agreed year of contract reached.
The big curious question pops up, Todd Boehly made a mistakes by appointing Enzo Maresca as headcoach? He's yet to make any big moves for the club. No evidence of improvement, however this is merely friendly games, he's trying out his tactics for the new season, so we shouldn't rush into conclusion regarding his position in the managerial role.
Enzo Maresca is new to the system, there's a lot for the new coach to accomplish. He's well positioned and experienced, he knows how to coupled up with the big advantages of the Blues. Though he's yet to grab his first winning in the pre-season games, the Blues have recorded a draw and defeat which never a welcoming odds for the manager and the new players signed.
experience is not an important thing as long as he can maintain cohesion team. There are many new coaches who are inexperienced out there but can win prestigious tournaments. Like example Pep guardiola who have new as coach barcelona senior at past, but he proved that he could and was even able to win the league with many achievements. Maybe now we need to wait first until the league starts, maybe there will be a surprise like what happened on new coach before.
