This was a tough away game for the Gunners. West Brom are a solid side that have been playing very well this season (as their win away at Man U last weekend attests). So, no disgrace that Arsenal came away with only one point from this fixture. Admittedly, the Gunners weren't at their fluid best; aside from a few moves of real brilliance, they looked like they have come off the boil a bit. Ramsey picked up a knock in the first half that forced him to retire early in the second half. His replacement, Thomas Rosicky, seemed completely off the pace. Jack Wilshire, aside from a well-taken half volley that careened off a West Brom defender for Arsenal's only goal, still is struggling to find his form. He misplayed several passes in the first have, and allowed West Ham defenders to get into his head with a lot of niggling fouls (as is too often the case). Giroud and Ozil showed great quality, once again. But they didn't get enough support in this match from the rest of the midfield.
That said, West Brom have to be given some credit for taking Arsenal out of their game. They made up for whatever talent differential that exists (and if it does exist, it's not all that great) with great effort, good passing, and a strong defensive shape that Arsenal found hard to break down. Either team could have taken all three points in this match, and West Brom might actually have had the better claim to them.
