Chelsea lacks an actual playmaker in the mold of Kelvin De Bruyne or Martin degaard. However, we have Enzo Fernandez, who is developing into a fantastic midfielder for the squad; it's just a matter of time before he approaches the standards of these tremendous players. Todd Boehly has made mistaken assumptions in the past, signing inconsequential guys who are completely naive about how to perform in elite clubs. Mykhailo Mudryk is a young player with potential for his new team, but I'm not sure what's causing his performance to decline.
Currently Pochettino is moving Enzo Fernandez from defensive midfielder become an attacking midfielder, if Nkunku already back, I think Enzo will back to his position. Both Sterling and Jackson can play as strikers, it's should be the best line up for Chelsea.
The problem about Mudryk is he can't move on from Arsenal, have a bad mentality and get pressured by every people since Chelsea spent too much money to sign him.
