Unai Emery’s Arsenal side have lost their last three league matches.

TEAM NEWS

Arsenal’s Laurent Koscielny is expected to be fit despite being substituted against Valencia because of fatigue.

Long-term injury absentees Rob Holding, Hector Bellerín, Aaron Ramsey, Denis Suarez and Danny Welbeck remain out.

Brighton winger Jose Izquierdo has been ruled out by a recurrence of knee cartilage damage.

Davy Propper is still sidelined by a hamstring injury, but Beram Kayal has overcome a similar complaint that forced his substitution last weekend.
