The speculations of Messi's return to Barcelona are now hitting up and it seems likely that a move can happen in the summer as Barcelona President has mentioned that the club is talking to Messi's camp and discussions taking place already. I think Barcelona is also putting in place measures to satisfy every financial fair play rules if Messi is to join eventually.
As much as they still all want Lionel Messi return when it's not really as smart as it seems even if he returns, he shouldn't be used for attacking options but rather for the attacking midfielder position.
My honest opinion is that Lionel Messi is a gone player, they can go ahead supporting him but Lionel Messi back to Barcelona is not just right thing to do.
President's at times talks and make comments only when it does benefit's. Messi can rather join the Saudi Arabian League instead of waiting.
