Bastian Schweinsteiger has left Manchester United but who could go next?
The report claims the Argentine is a big fan of the defender and doesn’t want a repeat scenario of trying to find a replacement for him in the summer following their struggles to replace Dani Alves last summer.
But despite Messi trying his best to keep the defender at the Nou Camp the decision ultimately lies with Alba.
The report claims the 28-year-old is waiting to see who will succeed Enrique at the end of the season before making a decision on his future.

Barca are unlikely to want to part with Alba though, who is under contract until 2020 with a buyout clause of £130m.
United are set to have to offer much more than £25m if the Spanish giants are to consider doing business with them in the transfer window.
