Arsenal are hopeful of Aaron Ramsey being fit to play again this season.
Ramsey will definitely miss Arsenal's clash with Crystal Palace amid fears he has played his last game for the club.
The Welshman had to be replaced during the first half of the Europa League quarter-final victory over Napoli on Thursday night.
Unai Emery admitted at full-time that he was unsure if Ramsey would play for Arsenal again ahead of his summer move to Juventus .
Arsenal will continue to assess Ramsey over the coming days to determine the extent of his hamstring problem.
