Are you trying to mock Chelsea and their fans or you're serious asking this question? 
Chelsea itself is not dreaming of being in the top four of the league table this coming season talk more of others. For someone to think Chelsea would finish in the top four with their recent condition is a fantasy. By the way, I see Conor Gallagher as average player as well but for Chelsea to allow the youngster to leave is the greatest mistake they would make this season and it would definitely affect them. Everything they are doing now is to maintain their position in the mid table and not get relegated.
Maresca is trying to change the team at his own discretion, Pochettino also allowed many players to leave the team after his arrival, I think it is normal when a team changes a coach. I understand that after Maresca managed to win the Championship with Leicester, he feels confident in himself, but the Premier League is a completely different level. He says that he wants to achieve the same greatness as City, but it will be much more difficult to repeat than to say so.
