Miretti has excellent off the ball movement. Unluckily for him, football is a game played with ball on the feet and he’s shit when he has ball on his feet.
He moves off the ball well and is allways available and mobile in the channels. That's literally only reason he is playing. He was better in that aspect then Fagioli first game.
But he seems like a complete brain fart as soon as he gets the ball and has time on it (better off just doing quick one pass).
