Strong rumors have emerged concerning Lionel MESSI's Argentina future the past few days. One of the stronger ones is that MESSI will no longer participate in friendly matches but only in competitive matches and tournaments.
Following Barcelona's match against Villarreal, word got out that MESSI has a muscle problem and will miss Argentina's match against Germany.
Concerning MESSI no longer playing friendly matches, my view on it is that it won't happen. The AFA already has clauses in their contracts where should MESSI play they will make more money. They also stand to lose a lot of money on it and I would find it difficult for the AFA to sell out or make revenue with MESSI not taking part in friendly matches.
The AFA is sponsored by Adidas as is MESSI himself and they would no doubt have a say in it. This is not for certain but it is the rumor in Argentina.
