Mesut Ozil, Theo Walcott and Olivier Giroud scored in the second half to take Arsenal back up to fifth place in the Premier League with a 3-0 win over West Ham United.
Ozil opened the scoring on 58 minutes when his left-foot shot deceived Hammers goalkeeper Darren Randolph.
Ten minutes later Ozil pulled the ball back for Walcott to finish neatly, before Giroud curled in a superb third from the right edge of the area after a burst upfield from fellow substitute Alex Oxlade-Chamberlain.
The result leaves Arsenal four points behind fourth-placed Man City, with a match in hand. The Hammers are five points above the relegation zone.
