Jack Wilshere, Mesut Ozil and Alexis Sanchez were among the Arsenal players who trained on Sunday ahead of their clash with West Brom.
Arsene Wenger's side welcome the Baggies to the Emirates on Monday night hoping to extend their perfect record on home soil this season.
Arsenal have already beaten Leicester, Bournemouth, Doncaster and Cologne at the Emirates this season, while West Brom have not won away from home in the league since the second week of the season.
Pulis' side have a horrendous record at Arsenal, too, having won only once of their last 14 visits to North London.
