Should Efain Juarez join Barcelona?(Details inside.)?

I think Marquez will stay since the two center backs are in Spain and will most likely go to the national team to play the Qualifying Rounds for the Euro 2012, and since they'll be tired, Guardiola will most likely put Marquez will Milito and Efrain Juarez would be a good addition, Jonathan will also play a lot this season since the whole midfield is from the Spanish National Team
