Wolverhampton Wanderers are seeking a fourth successive win which would take them above Chelsea in the table.
A third consecutive victory would move Arsenal within three points of their opponents and boost their chances of securing European football next season.
Team news
Wolves have no fresh injury concerns following their 1-0 win at Aston Villa.
Lucas Torreira is available for Arsenal, but Mesut Ozil (back) will be assessed.
Bernd Leno, Calum Chambers, Gabriel Martinelli (all knee) and Pablo Mari (ankle) remain sidelined for the Gunners.
