Arsenal scored three goals against London rivals West Ham as they claimed all three points at the Emirates and moved above Manchester United on goal difference.
Both Petr Cech and David Ospina are currently out for Arsenal so Emiliano Martinez made his first Premier League appearance since 2014. Michail Antonio returned for West Ham.
Chances were few and far between in the first quarter of an hour with neither side creating anything of note. However, in the 18th minute, Theo Walcott was fouled by Arthur Masuaku in the penalty area and went down. Referee Martin Atkinson did not see anything wrong with the challenge and waved away the protests. West Ham had attempts on goal from Mark Noble, Manuel Lanzini and Michail Antonio but they were all wide. Arsenal’s best spell of the half came in the 40th minute. Alexis Sanchez found Mesut Ozil but James Collins slide in at just the right moment to deny the German. Hector Bellerin, Mohamed Elneny and Walcott also failed to convert very good chances so it was scoreless at the break.
The returning Michail Antonio made way for Robert Snodgrass as West Ham made their first change during the break.
The Gunners kept up their intensity in the second half and the breakthrough came in the 58th minute. In his 150th game for Arsenal, Mesut Ozil made it an occasion to remember. The German curled a left footed shot into the bottom corner leaving Randolph helpless.
Diafra Sakho made his return in the 63rd minute for West Ham, taking Andy Carroll’s place.
Ten minutes after giving Arsenal the lead, Mesut Ozil was at it again. This time he provided an assist for Walcott. It was a trademark Arsenal team goal with a superb build up. Sanchez found Ozil with a back-heel and then he put in a low cross for Walcott who doubled the lead from close range. Walcott made his 200th appearance at the Emirates and captained the side in Laurent Koscielny’s absence.
Having got more minutes on the clock as he works his way back to full fitness, Danny Welbeck came off in the 74th minute and was replaced by Olivier Giroud. Lanzini tried to make something for West Ham when he beat two Arsenal players and fired a shot at Martinez but the Arsenal keeper was equal to it.
Arsenal made their final changes with nine minutes remaining. Aaron Ramsey and Alex Oxlade-Chamberlain returned to the side as Elneny and Walcott made way. Just two minutes after coming on, Oxlade-Chamberlain combined with fellow substitute Giroud to make it 3-0. The Frenchman curled his shot into the far corner and secured all three points for the Gunners while consigning West Ham to their fifth consecutive defeat.
