"I feel fine, but I don't know yet if I will be available for Sunday," Messi said at a promotional event at the Nou Camp. "I'll see. I am grateful for all the messages of support I have received."
Messi came on in the 58th minute of Wednesday's tie only to collide with Benfica goalkeeper Artur Moraes six minutes from time in a match that was meaningless to Barcelona but where he was chasing his 85th goal of the calendar year which would have equalled Gerd Mueller's long-standing record.u00a0
