Played him RB in my Arsenal only team this WL. He was actually really disappointing. Obviously I didn't expect much... but damn he sucked.
Honestly, none. Even his 'not cons' like his pace, passing and dribbling are so mediocre it's unreal. He isn't rapid, he is barely fast even with a shadow.
Tackling is slightly better than mediocre I guess. but that's it. His other defensive issues mean he is still pretty bad.
Physical - He is the weakest fullback I have ever used.
Work rates - Even on stay back he is NEVER in position unless you manually position him.
Shooting - He will get into positions, even when he is stay back. Doesn't matter though, he will miss.
Stamina - He gets quite tired by the end of the game. Sad really.
