Theo Walcott who limped off against Doncaster Rovers mid-week in the League Cup also played a full part in team training.
In the last five matches, Arsenal has three wins, one loss, and one draw whereas the team West Bromwich Albion has one win, two loss, and two draws.
The 36-year-old, who made his professional debut for Aston Villa in 1998, will play in his 633rd top-flight game and break Ryan Giggs' record if he features on Monday night.
