Barcelona have revealed Lionel Messi is a doubt for Saturday's derby against Espanyol.

The Argentina forward suffered a sprained ankle late in last night's UEFA Champions League win over Dynamo Kiev courtesy of a fierce tackle from Leandro Almeida.

Moments earlier, the FIFA World Player of the Year nominee had sealed Barcelona's 2-1 win with a superb free-kick four minutes from time. He continued to pull the strings thereafter, but one trademark run was brusquely halted by Almeida.

Barca revealed on their official website, fcbarcelona.com: "The resulting sprain means he may well miss this weekend's match, with just three days to recover. "His availability depends on the club medical services."
