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.
Since messi is not yet extending his contract with PSG and this kind of rumor will always come probably until he ends of the summer transfer season. it's caused by messi is not yet getting a club since he has been rejecting a new contract from PSG. Messi is as big as ronaldo. Any news about him will be consumed widely by so many people in the world. barcelona is also spreading the news about its president already making call to the messi. that was making the public believe if messi will be back again in barcelona.
According to media reports, Messi's wife and children want to return to Barcelona. In fact, there were reports earlier that they were having a hard time adjusting to their life in Paris. However, Messi continued to stay at Paris Saint-Germain FC. But this time his contract expires at the end of the season. Pressure from his family may also be effective in his new decision. Therefore, if he does not stay in Paris Saint-Germain FC, I do not think he will go to the Arab League. It is very likely that he will return to Barcelona again.
