I think he has less brain-farts a la Zebina and is better in the air. I think physically they're about even, he's slightly stronger than Marquez but Marquez is slightly quicker.
andrade and chiellini, if legro keeps his form up, count him too. plus, we already have a super-aggressive guy who ia always a risk for yellow and red cards, we don't need another, especially with our relationship with the referees.
