I think we made the right choice in signing Melo over Dago, but in a 4-3-1-2 I still think Dago would be great, and if we had signed him I think he would have done great playing besides Sissoko and Marchisio. I still think Dago is better offensively than Melo, but Melo is a better overall player. In a 4-2-3-1 like I expect Madrid will play I don't think he'll be a success though. That formation requires two hard working midfielders, especially behind the likes of kaka, ronaldo etc. In fact I think Madrid would have much more use of a player like Melo than Dago in their team.
