Arsenal will be without Thomas Partey for Sunday's Premier League visit of Leeds.

Kieran Tierney (leg) is also still missing but both Bernd Leno and David Luiz are back in contention after serving one-match bans following their red cards against Wolves.

Rodrigo and Pablo Hernandez have not recovered from respective muscle strains and will not be included in the squad.
Winger Ian Poveda (ankle), plus defenders Diego Llorente (muscle strain), Robin Koch and Gaetano Berardi (both knee) are still out.
