Two goals apiece for Olivier Giroud and Santi Cazorla were enough for Arsenal to comfortably see off Newcastle United and extend the Magpies’ miserable run at the Emirates. Giroud gave the Gunners a half-time lead with a fine header before the home side moved through the gears to take a three-goal cushion. Ayoze Perez pulled a goal back for Newcastle with a fine header from Jack Colback’s free kick but Cazorla’s penalty ensured Arsenal were clear winners. Much of the build up to the game centred on Arsenal’s supposedly horrendous injury problems. Arsene Wenger was unable to call upon Mesut Ozil, Laurent Koscielny and Calum Chambers amongst others, meaning former Newcastle played Mathieu Debuchy played alongside Per Mertesacker in the centre of defence. However, when you can still field a side boasting Alexis Sanchez, Danny Welbeck and the aforementioned scorers, it becomes somewhat difficult to show sympathy to such a strong side that had far too much for Newcastle from the first whistle. Mertesacker was the first to go close for the home side, heading a corner onto the crossbar with young goalkeeper Jak Alnwick well beaten. After that let-off, Newcastle then shot themselves in the foot when Fabricio Coloccini misplaced a pass after 15 minutes. Hector Bellerin intercepted and after Giroud found Sanchez, the former Barcelona winger stood a perfect cross up for the Frenchman to power home a stunning header. Arsenal – buoyed by their 4-1 success over Galatasaray in midweek – continued to dominate possession and Newcastle looked a far lesser threat without powerful midfielder Moussa Sissoko who was serving a suspension. However, Newcastle enjoyed some success from set pieces and could have had an unlikely equaliser when Colback’s free kick caused confusion in the home box. Yoan Gouffran’s header was repelled by Wojciech Szczesny and with the Polish keeper on the floor, Papiss Cisse lashed a shot towards goal only to see it come back off the stopper and rebound to safety. Alan Pardew made two early changes in the second half with Cabella and Emmanuel Riviere being introduced and it coincided with Newcastle making a bright start to the second period. The visitors enjoyed more possession and found themselves in decent positions at times but didn’t have the goal threat to trouble Arsenal and were soon caught out on the counter attack. Cazorla was the beneficiary of a fine pass from Sanchez and hurdled a sliding Coloccini before chipping a delightful effort past Alnwick with his left foot. The goal seemed to knock the belief out of the visitors and when Giroud added a third with another excellent finish, there was the potential for another heavy Emirates defeat for Newcastle. Pardew’s side did get a goal back though, as Perez took advantage of some poor marking to glance a header home from Colback’s latest free kick for his fourth goal of the season. But Arsenal re-established their cushion when Paul Dummett brought Welbeck down inside the box and Cazorla confidently chipped the penalty past Alnwick.
