Mikel Arteta has revealed his concern over the form of Arsenal striker Pierre-Emerick Aubameyang.
The Gabonese striker failed to score again as Arsenal succumbed to a 2-1 defeat to Wolves in the Premier League.
He spurned a few decent chances in the game, including a header 10 minutes from time that would have earnt the Gunners a point.
Aubameyang has just one goal from open play in the league this season which came on the opening day against Fulham.
Since then he has only managed one further goal in the league which came from the penalty spot against Manchester United at Old Trafford. He is still yet to score at the Emirates Stadium this season.
It was argued that this was due to the fact that the 31-year-old was playing on the left wing. However, Mikel Arteta has moved him down the middle for the Arsenal's last two games and he has still failed to find the back of the net.
Speaking after Sunday's loss the Arsenal boss revealed this fears over the form of his top marksman.

"Well I think we all are because the main goal scorer of the club at the moment is not scoring goals" he said when asked if he was worried about Aubameyang's dry patch.
"My biggest concern is how to help him to score more goals because we need his goals.
"How important Auba has been for this club in the last two years, and how the goal sheet has been shared amongst the squad tells you the importance of him scoring goals if we want to be successful."
The Gunners have become heavily reliant on Aubameyang for goals in recent times. Last season the former Borussia Dortmund man scored just under 40% of their goals in the Premier League. Only Southampton were more reliant on one player in Danny Ings
Without him firing Arsenal have managed just 10 goals in 10 league matches this season. They currently sit 14th in division and have lost five games already.
The club's other striking options are also out of form. Alexandre Lacazette hasn't scored since September, while Eddie Nketiah has managed just one league strike all season.
Young forward Folarin Balogun has the club's best goal-to-minutes ratio after scoring within seconds of coming on as a substitute against Molde in the Europa League on Thursday. However, 19-year-old is considered too raw to be included in the Premier League squad currently.
