He looks like he's strong and can win headers but I'm not really seeing anything else from him. He has no pace, can't beat a man, doesn't run in behind, and his movement is just ok.
He looks like the type of striker who will do well if you create plenty of chances inside the box, a bit like Hwang, but he hasn't shown any great finishing as of yet when presented with chances. I'm not sure he can mix it with pacey dribblers around him and link successfully with them in an effective way tbh.
I think it's another systemic thing whereby no big target man is ever going to look great in this team. I'd rather have someone quicker with better movement. It may be why a player like Guedes has got 3 goals in 2 games in the cups.
