Messi returning "is up in the air; it'll depend what he wants"

Barcelona manager Xavi understands the 'Cule' fans' desires to see Messi back at the Camp Nou, and he was asked about the possible transfer in the press room ahead of the side's away game to Real Valldolid this Tuesday.
As much of the footballing world have already expressed, the Barca squad have also made it clear that they want the man from Rosario back, and current boss Xavi appeared no different.
When asked about it specifically, Messi's ex-teammate said any possible move "is up in the air", with it "depending on a lot of things, mainly what Leo wants".
With these comments, then, one could assume that Barcelona have put the ball back in Messi's court, with the club letting him decide what he wishes to do once his contract at PSG ends.
