Arsenal manager Mikel Arteta is unconcerned by Pierre-Emerick Aubameyang's goalscoring form.

The Gabon striker, who signed a lucrative three-year extension this summer, has scored just once in five appearances this season.

"With all the strikers if you ask when they don't score for two or three games if there are concerns, in my opinion the performance was not a cause of this," Arteta said ahead of Thursday's clash with Rapid Vienna.

"He could have scored again on Saturday in a one-vs-one situation that normally he does. It's trying to get in better positions as frequently as we can to try to give him the best possible chance."
