Contepomi has made no decision yet. I don´t think he´ll play again to be honest. Its similar to Pichot after 2007 when he didn´t retire until mid 2008 despite never playing another test after the World Cup.
A crash ball centre is possible but there is nobody of note. Avramovic for instance. The guys in the Pumas backs these days are all former Sevens players. RodrÃguez, Camacho, González Amorosino.. They won the 2009 USA Sevens. A hard running centre can be replaced by putting a big guy in the backs in broken play or lineouts. Stick Creevy there or Leguizamón. Scotland did this well a few years ago.
González Amorosino can play wing and fullback as you know. The same is true of Bustos Moyano and Horacio Agulla. They could mount a good strategy to utilize this well.
Albacete is out for 2 months right now with a broken ankle sustained on Saturday. He´ll be back and as captain I think. He´s on contract with Toulouse until RWC 2015 then he wants to join a Japanese club.
Argentina are to host France in June 2012 in a three match series and then have the Four Nations. So, they´ll certainly be testing out different players. Its not official yet but looks like the European based players, esp the English, will have a maximum of five matches each during the Four Nations. So the team will have to swap a bit.
MartÃn Bustos Moyano will certainly play but maybe not initially. It´ll depend on who is in the Top 14 Semi Final and moreso the Final itself as those players will certainly miss the first French testmatch. the Top 14 Final will be on June 09 so realistically those involved will only play the third match. France could be spanked if it is a Toulouse vs Clermont final. It would mean no Vergallo and Albacete though too. They will, at best, be on the bench
Vs France for the initial match it may be something like:
15 Lucas González Amorosino
14 Gonzalo Camacho
13 Marcelo Bosch
12 MartÃn RodrÃguez Gurruchaga
11 Juan Imhoff
10 Juan MartÃn Hernández
9 AgustÃn Figuerola

20 Alfredo Lalanne
21 Santiago Fernández
22 MartÃn Bustos Moyano
