Riquelme, Banega, Pastore, Nicolas Gaitan, Ricky Alvarez, Angel Di Maria, Erik Lamela, Gago, Mascherano, probably more. I can't remember.
I am talking about central middfielders not wings or attacking middfielders and the only ones i see there are mascherano , gago and banega .
Riquelme attacking middfielder , old , will be benched
Banega , don't know him that well
Gago , sucks
Mascherano , the best they have
Alvarez , sucks and will be benched
Di maria will play
Lamela , is a ss , will be benched
Pastore , plays as amf ,ss will be benched
Gaitan amf , will be benched
The attack of argentina will be made of players between messi , aguero , higuain , tevez , di maria , every other wing/amf/ss will be benched , probably some of the ones you mentioned won't even be on the bench . Right now argentina is overflwoing with ss/amf/wingers
Considering that the names i mentioned are very offensive i would play 2 good defensive middfielders , they have one in mascherano they need another , gago is not it and haven't seen much of banega to give a judgment . Than there is the defensive problem , i strugle to think of any good defenders they have
I supspect they will play with a 4231 with higuain/tevez up top , messi on the right , di maria on the left , aguero at amf , mascherano in middfield and he needs a partner ?
