Dalot and AWBs offensive output is similar but Bissaka eclipses him. Dalot has played less of course and has room for improvement considering his age but to suggest Bissaka has offered nothing in attack is just silly. Dalot could only dream about Valencias output as well wouldn't you say?
His crossing is less than impressive, usually over hits them. I wonder why crossing is considered his best attribute when it's clearly not. Many on here have bemoaned his hit and miss crossing on matchday. He's good on the ball but doesn't have one outstanding attribute
Perhaps it's the former
