Missing Players and team news:
Villarreal midfielder Trigueros is fine to play in this match despite his red card in domestic action, but his fellow lynchpin Vicente Iborra remains out with a knee issue. However, Emery has no other injury concerns apart from Iborra, and Francis Coquelin will also hope to get one over his old club, but he may be restricted to a place on the bench as Dani Parejo and Etienne Capoue continue in the engine room. Tottenham Hotspur loanee Juan Foyth should continue at right-back, while Pervis Estupinan made his comeback from injury off the bench against Barcelona and will hope to displace Alberto Moreno on the opposite side. With 26 goals in all competitions to boast this season – as well as six from his last five in Europe – Gerard Moreno will be out to register a goal contribution for the seventh game in a row in the Europa League this week. Arsenal received a huge boost against Everton as Martin Odegaard returned to the fold following ankle trouble, but Alexandre Lacazette – who struck twice in the second leg against Slavia Prague – is expected to miss out with a hamstring problem. Pierre-Emerick Aubameyang may return after recovering from malaria but is unlikely to be risked from the off, and the Gunners remain without long-term defensive absentees David Luiz and Kieran Tierney for the first leg. Gabriel Magalhaes will hope to replace Pablo Mari at centre-back, while Nicolas Pepe’s spot could be at risk if Odegaard returns, but the Ivorian has played a starring role in the Gunners’ Europa League campaign so far.
