Former Barcelona coach Carles Rexach says it's crucial they keep hold of Lionel Messi.
Messi's contract is set to expire in June.
"Thanks to God, he's been the solution to Barcelona's problems," Rexach reacted on Radio MARCA.
"For me, he didn't do the right thing with the burofax, I have to say, although I'm pro-Messi all the way. That hasn't benefited anyone.
"I think he'll stay at Barcelona if he doesn't decide to play at another level, like leaving for Qatar, for example."
