Arsenal face a tough weekend assignment in the form of West Ham as they look to keep their bid for a top four finish on track.
Unai Emery's side make the short trip east to the London Stadium and know they can ill-afford to drop more points with Chelsea and a resurgent Manchester United proving formidable rivals.
For West Ham, their week has been dominated by transfer speculation around striker Marko Arnautovic and having rejected a £36million offer from China, the club will hope the Austrian can shift his focus back to matters in the Premier League.
