Arsenal manager Unai Emery was left to rue his side's missed chances as the Gunners slipped to a disappointing 1-1 draw with Brighton at the Amex Stadium on Wednesday.
After taking the lead through Pierre-Emerick Aubameyang's classy first-time finish, the Gunners were made to pay for failing to take advantage of their early dominance.
A Brighton counter-attack saw Stephan Lichtsteiner misjudge the flight of the ball and only manage to glance his header into the path of Jurgen Locadia, who took it around Gunners goalkeeper Bernd Leno and score for the equaliser.
With Aubameyang missing a further two opportunities, Emery was left frustrated at his side's inability to convert their chances in the first-half, and admitted they struggled as the game wore on.
