The 'Gunners' took part in a light session on Sunday afternoon ahead of the clash, which could see Arsene Wenger's side jump five places in the Premier League table and move into seventh.
Arsenal have been in decent form on home soil so far this season, beating Leicester, Bournemouth and Koln, whilst West Brom's away record leaves something to be desired.
Jack Wilshere was picture taking part in the session, with the 25-year-old available once again after recovering from a leg fracture, whilst Alexis Sanchez looked to be putting in a shift following his reintegration into the squad.
