Support and patience is what he really but that is not something we know Chelsea management with, right now Maresca needs their full support. According to stats Maresca is a coach with potentials we saw what he did at Leicester City last season bringing them back the premier league and winning the Championship title in his first season, not just that he changed the teams style of play entirely which means he is a coach that can influence a team easily unlike Pochettino.
Maresca did succeed in bringing Leicester City back to promotion to the Premier League, but the competition in the Premier League will be much tougher because there are many strong teams here.
Becoming a coach of a top team is also not easy because he will feel a lot of pressure. Maresca does need support from management and fans, but it depends on how he succeeds in bringing Chelsea to play more consistently.
Maresca's task is not easy and we can see how every coach will experience difficulties in the Premier League.
If he doesn't want to suffer the same fate as Pochettino then he must try to show change for Chelsea.
Chelsea management will support Maresca with huge funds to bought the players to strengthen Chelsea squad but i don't think Chelsea management will have enough patience to see Chelsea performance decline under Maresca someday and i am sure Maresca will get the same treatment as the previous Chelsea manager that he will most likely be sacked as well and actually under Mauricio Pochettino Chelsea progress was very good but Chelsea owner didn't satisfied and sack Mauricio Pochettino so these things will happend to Maresca too because next season if he unable to bringing Chelsea to performing well then i am sure Maresca will be sacked too
Chelsea in Todd Boehly era was very crazy that Todd Boehly will never hesitate to give a lot of money to the managers to build the squad but he also will never hesitate to sacked them who failed to bringing Chelsea to performing well and since Todd Boehly taking over Chelsea he was total sacked 5 managers which the latest is Mauricio Pochettino and about Maresca i think he has put himself in a very difficult situation and in my opinion the position as Chelsea manager is the most stressful position if we compare it with other managers in the Premier League
