Enzo is a flawed player. His base technical skills are great but he is seriously inagile and slow, he is basically unable to carry the ball, I don't think I've seen him go on one decent dribble since he joined Chelsea.
If he gets the ball it's already left his feet in the next 2 seconds. Just a distribution machine with no legs which is basically what Jorginho was for them, just younger.
Against teams with a good press or in games where they suffer in attack and he has limited options going to be shut down as can't create space with the ball on his own devices.
