Yeah because Maguire decided not to mark Van Dijk Maguire's job is to be in the 5 yard box and head the ball away. Maybe it was better if he marked Van Dijk, but Ole is clearly not interested in that.I also think it has to do with the defenders he plays with. Maguire and Lindelof are piss weak. Lindelof in particular is dreck. De Gea called more than once for a ball but Lindelof never listened. Lindelof can't jump. No aggression. Then you've got Maguire who leaves the biggest meanest opposition player unmarked and takes three touches in his own box like an oaf and turns like an oil tanker to pass it back to the keeper.
The save he made from Henderson was unreal. Pity no one will remember it a decade from now. The one from Mane was excellent too. Most keepers would have gone with their hands.
