Watford and Arsenal are out of their comfort zones. Marco Silva’s side have not won yet at home and Arsène Wenger’s have not won away from the Emirates. However, it is surely Arsenal that should be more confident, despite in all likelihood missing Alexis Sánchez, of breaking their duck after not conceding a league goal in September. Petr Cech will need to be at his best to keep another clean sheet though as Richarlison is going to be eager to continue impressing. Graham Searles
