Arsenal might likely be without two key players ahead of the visit of Italian Serie A club Napoli in the Europa League.
Laurent Koscielny and Granit Xhaka are two of the five captains at Arsenal alongside the likes of Pete Cech, Mesut Ozil and Aaron Ramsey and both players could miss the Napoli with respective injuries.
In his pre-match thoughts ahead of the Napoli game, Arsenal manager Unai Emery told reporters that the two players are doubtful for the Napoli game before adding that he will have to wait till tomorrow to decide if they would part of his squad for the crucial clash.
Laurent Koscielny and Granit Xhaka both missed the last two games for Arsenal with foot and groin injury respectively.
They were absent from the Arsenal team that moved into third place on the Premier League table after a 2-0 home win over Newcastle United last week Monday.
Both players also missed the 1-0 league defeat at Everton on Sunday.
Laurent Koscielny has been battling with small injury problems since he returned from a long-term Achilles injury towards the end of last year while Granit Xhaka sustained a groin injury while he was on international duty with the Switzerland national team.
Arsenal will be hoping to secure a first leg advantage against Napoli ahead of the second leg in Italy next week.
