Arsenal forward Gervinho has admitted that he needs to improve his performances in front of goal.

The Ivory Coast international was sarcastically cheered by Gunners fans when he was taken off during Wednesday's Champions League defeat following a disappointing display up front.

"I am working very hard at training to improve my efficiency, to be more clinical in front of goal," the 25-year-old told the club's official website. "It has been my flaw so far.

"I know I still have a lot more to learn but I am more confident now - the start of the season and my goals so far have showed that I have improved a lot."

Gervinho is Arsenal's top scorer in all competitions so far this season with five goals.
