Nahki Wells was not in the Burnley team that watched Alexis Sanchez converted a stoppage-time penalty as Arsenal snatched all three points in a 1-0 win at Burnley.
Burnley defender James Tarkowski was penalized for his shove on Aaron Ramsey in the 91st minute and Sanchez made no mistake from the spot to clinch Arsenal just their second league win on the road this season.
It was cruel on Burnley. Arsenal skipper Laurent Koscielny struck a controversial winner in time added on in the corresponding fixture last season and Sanchez's late spot kick sank Sean Dyche's side at the Emirates in January this year.
