Personally, I hate Marquez but you have got to admit he's a great player. Rafa is a fantastic leader who used to be one of the best centerbacks in the world until Rijkaard started using him at defensive midfield. I really can't stand Mexican players and he can be a bit dirty at times, but honestly, to compare him with Legrottaglie or Boumsong is just nonsensical... the guy blows anybody we have at the back out of the water. Moreover, he would really improve our distribution out of the back as well.
I say lets get him as whoever wrote that Goal.com article is right... we have to be realistic here and look for good deals. And besides that, Marquez is better than Barzagli.
