To be fair can't remember Barca conceding that many goals from corners and set plays both domestically or in Europe. He played there for a long time if height is the only thing that matters heading the ball it would surely have been found out. Gary Neville was a fantastic header of the ball it's mostly down to strength, position and timing. Mascherano had all of these attributes, Kounde won't get bullied he is built like an ox and clever as well. But that won't matter because we aren't paying 70m for him.To be fair that wasnt down to Mascherano's height and it was more due to the opposition not having enough possession to make an attack.
