Arsenal go into the second leg of the Europa League quarter-final against Napoli having won the first leg 2-0 over Carlo Ancelotti’s side.
Lucas Torreira will undergo further assessments before Arsenal fly out to Naples after he sustained an injury which is understood to be a groin damage.
Denis Suarez is also suffering with minor groin issues though it is a matter that is open to debate whether Emery would take the Barcelona loanee on the trip.
Arsenal's only injury concerns are long-term ones, with Danny Welbeck, Rob Holding and Hector Bellerin all expected to miss the remainder of the season.
Unai Emery is expected to revert back to the three man defence as Sokratis Papastathopoulos will also miss the match due to suspention for the next Premier League game.
Arsenal are acutely aware that they cannot necessarily rely on their defence to stop Napoli from overturning the two goal deficit so Emery is set to name a competitive squad capable of taking the game to their hosts.
