Mikel Arteta must do without Bernd Leno, Calum Chambers, Pablo Mari, Gabriel Martinelli and Shkodran Mustafi for the final day welcome of Watford. Reiss Nelson and Mesut Ozil will be assessed, but Matteo Guendouzi remains absent having been disciplined by the club. After a disappointing performance at Aston Villa, Arteta is expected to ring the changes, with Kieran Tierney, Granit Xhaka and Nicolas Pepe among those set to come into the side. Hayden Mullins has no fresh injury issues for their must-win trip to Arsenal and remains without Daryl Janmaat, Isaac Success, Gerard Deulofeu and Etienne Capoue. He could make a couple of changes to the side that was dismantled by Manchester City on Tuesday. Indeed, Nathaniel Chalobah and Danny Welbeck are two who are expected to start here.
