Arsenal romped to a 4-0 victory at home to out-of-form Watford to keep their Premier League title hopes alive.
Gunners boss Arsene Wenger named the same starting XI who won 2-0 at Everton before the international break while the visitors showed three changes to the side beaten at Stoke City, with Sebastian Prodl, Ben Watson and Almen Abdi given starts.
The home side took just four minutes to break the deadlock when Alex Iwobi picked out Alexis Sanchez with a cross and while his initial header was saved by Heurelho Gomes, the Chilean made no mistake from the rebound.
Gomes then made a fine save to deny Iwobi from distance and Danny Welbeck saw an effort deflected wide as the home side turned the screw and went in search of a second goal.
The visitors were struggling to create much in attack, with David Ospina enjoying a quiet afternoon in the Gunners goal.
And seven minutes before the interval it was 2-0 to the hosts as Sanchez turned provider, finding space to pick out Iwobi who gave Gomes no chance with a calm finish.
Three minutes into the second half the hosts moved three goals ahead when a Hector Bellerin effort was deflected past Gomes by Watson and soon after Iwobi smacked a shot against the bar
Mesut Ozil and Sanchez then forced former Spurs man Gomes into further saves before Prodl almost pulled a goal back, only for Nacho Monreal to clear from close to his own line.
Twenty minutes from time Ospina had to block a Troy Deeney effort following good work from Nathan Ake.
The Gunners had the final word as Theo Walcott converted a pass from Joel Campbell at close range to make the final score 4-0.
