Movement, passing, vision, anticipating danger, passing the ball and then moving to receive another pass (watch McGinn he rarely does this if ever) , he's very good at intercepting the ball too. He actually can play for the full 90 minutes ,McGinn usually blows out after 30/35 (watch today's game again).
I like McGinn he's a great guy good banter but he is definitely not the best midfielder at the club - Douglas Luiz is. As I said he's a first 11 Brazilian player and McGinn plays for Scotland.
Only attributes I'd take of McGinn over Luiz are his tenacity and shooting. However because he lacks the stamina to produce or pace himself for 90 minutes his tenacity is wasted as he can't use this beyond a half.
Nothing personal Im just commenting on his footballing ability. Even Allan ghosted behind him and left him for dead the other day. Allan! I'm bloody quicker than Allan and I'm 15 stone full of Donner kebabs and pizzas.
