We conceded a 94th-minute goal to lose on the road at Brighton in a match overshadowed by what looked to be a serious injury to Bernd Leno.
Our goalkeeper went down after claiming a ball on the edge of the area, and immediately looked in trouble. After lengthy treatment, he was stretchered off with his right leg in a brace.
It was another frustrating moment for Mikel Arteta, just days after losing Pablo Mari and Granit Xhaka, in a game where he was looking for a response from his side.
We started much the brighter of the two sides with Pierre-Emerick Aubameyang having two early sights of goal before Bukayo Saka hit the bar with a brilliant curling effort.
