Yet the Gunners were short on confidence and ideas - while Mat Ryan produced a superb save at the end to frustrate the home side further. The Brighton keeper flung himself across his line to keep out substitute Gabriel Martinelli as Arsenal, who have home games against Manchester City, Chelsea and Manchester United on the horizon, failed to win for the 11th time in 15 top-flight attempts. The home side's night was summed up towards the end of the first half when Pierre-Emerick Aubameyang had a go at team-mate Joe Willock after a home move had broken down.
