Is Barcelona really Lionel Messi's only European option if he leaves PSG?

For the fourth game in a row, Barcelona fans at Camp Nou stopped singing club songs in the 10th minute as their side took on Atletico Madrid on Sunday. Instead, the 90,000 supporters in Barca shirts began chanting Lionel Messi's name, a chorus calling for the Argentine's return to Catalunya.

Club officials, meanwhile, have made no secret of their shared desire to bring Messi back to Camp Nou, publicly admitting in the past few weeks that they are in active negotiations to secure a sensational homecoming for a club legend.

And with a Paris Saint-Germain exit now looking increasingly likely, the Blaugrana might just fancy their chances.

After all, it does make a lot of sense. The door has always been open to a Barcelona reunion for Messi, especially given the fact that he never really wanted to leave anyway. Add to that the fact that Barca need someone to offer creativity in the final third, and there is a meeting of tactical sensibility and football romanticism here.

But there are other clubs out there who also wouldn't mind having Messi on their payroll, though it would be a complex agreement to come to. Messi would likely command wages in the range of his current PSG deal, with the Ligue 1 leaders paying him around €37 million (£33m/$41m) per year.

He would also need to be enticed by a viable sporting project. Champions League football is a bare minimum, and Messi would likely want to be in a situation where he could compete for a league title, too. That rules out most of Europe, with only a few clubs capable of making this deal happen.

But if not Barcelona, then who will Messi play for? GOAL takes a look at some of the Argentine's options...
