Aerially strong, a strong tackler, and an overall aggressive defender, Caleta-Car is a player who can excite the fans with his style. Despite not being that great on the ball, he's no liability like Smalling is; people had doubts over Skriniar's ability on the ball, but he's not done so badly in Inter's back 3.
My main concern with him is on how tunnel-visioned he gets with his defending. Because he's so committed, he can potentially be easily bypassed if the opposition disrupt our defensive shape, sort of like Smalling, Skriniar, Joe Gomez, Koundé, and Kabak.
