Well i would have to say i feel the opposite. I play against a friend offline, and he is a good dribbler, he has good skills with the ball.. he picks barcelona because of Henry, Eto'o and Messi. When i choose to mark either of them (Normal or Aggressive), my friend seems to have an easier time getting through them. I think its because my defenders stick close to whoever they are marked to. I feel like that makes my defenders useless, because all it takes is one through pass and no defender has a chance at catching any of those 3 in a foot race...
