It was the Baggies that needed the win, but Arsenal weren’t prepared to be generous. Before five minutes had passed, Lukas Podolski had given the visitors a bit of a scare, but his effort went wide of Ben Foster’s post.
The Gunners’ shaky defense was exposed early on, when Saido Berahino easily slipped behind the back line. His low shot hit the heel of Laurent Koscielny, however, and Wojciech Szczęsny was able to make an easy save.
That must’ve served as a wake-up call for Arsenal, because they took the lead before the 15th minute. A shot from Santi Cazorla was deflected out for a corner, taking by Cazorla himself. Olivier Giroud shook off his man, heading past Foster to give the hosts the lead.
West Brom steadily worked their way back into the half, while Arsenal gently drifted off to sleep. Graham Dorrans woke them up with a sharp strike from 25 yards, which must’ve stung Szczesny’s palms as he pushed it away. It fell to Berahino, but the forward could only balloon his shot well over the bar.
The rest of the half trailed off into nothingness, so it came as a relief when the Albion started pressing harder after the restart. Yet, despite their need to find safety, West Brom couldn’t find a decent effort.
With 20 minutes left, the Baggies were able to make a little noise. Morgan Amalfitano broke through the Arsenal defense, going one on one with Szczesny. The goalkeeper somehow managed to keep it out, with the aid of Per Mertesacker. Craig Dawson got his head on the end of the resulting corner, but it went high.
Arsenal looked like they were set to double their lead, with Podolski close in on goal. He couldn’t quite connect, but somehow the shot drifted into the post…and drifted right back out again.
The visitors continued to make their presence felt, but could only come close – their best effort a narrowly high header, again by Dawson, in the 86th minute.
