IMO he can't do that well. When he attempts to close a player down he runs at the player at the wrong angle, he doesn't block off a pass, so the player he is closing down just passes it straight past him. 101 of football, how to close a player down, it's the first thing you learn because it requires no skill.
It was incredible to watch last night, my mate laughs that he is a better footballer than Paulinho, he is certainly a more intelligent one, god knows how he gets in the Brazil team.
There was this kid who used to play football for my team when I was about 14 years old who was quick but brain dead, when we were attacking he would run back to our goal, when we were defending he would go forward, my dad used to joke that he needed him on remote control, he reminds me of Paulinho.
