Barcelona No2 Jordi Roura admits Lionel Messi is touch-and-go for their Champions League semifinal with Bayern Munich.
Messi is battling to overcome a hamstring strain.
"He's been feeling well. It looks as though his recovery is on the right track," said Roura.
"We'll see how he feels during today's training session and we'll talk to the doctors [before we make a decision]. Obviously, it's noticeable if you can't use a great player."
