Former Tottenham striker Darren Bent has questioned the form of Arsenal captain Pierre-Emerick Aubameyang.

The Gabonese forward, who found the net 22 times in the Premier League last season, delighted supporters of the club when he committed to a new three-year contract at the Emirates last month.

Since then, however, Aubameyang has not scored for the Gunners, and he cut a peripheral figure again as they lost 1-0 to Manchester City on Saturday.

Bent told talkSPORT: "It's not the fact he hasn't scored a goal, it's the performances.

"Before he signed his contract he was absolutely everywhere - running back, tracking back, putting tackles in, breaking forward. There was a real hunger and intensity to his game.

"At the minute, you can see there's been a massive drop off. I don't know if it's coincided with the new contract, but you can tell that he's not playing with the same intensity that he had before.

"When you focus so much on getting a new deal like Aubameyang did, you'll run that extra yard and make that extra effort.

"When he sits down now and analyses his performances before and after the contract he'll see that there's been a massive change."
