Borussia Dortmund striker Pierre-Emerick Aubameyang has warned Arsenal that the best from him is yet to come ahead of their Champions League clash.
The Gunners have enjoyed a perfect start to their European campaign with victories over both Marseille and Napoli, despite many predicting the club could struggle in a relentlessly competitive group.
After the disappointment of last season coupled with the loss of influential playmaker Mario Gotze, Jurgen Klopp's side have wasted little time in attempting to rectify those shortcomings, enjoying a thrilling start to the Bundesliga where the sit second, a point behind Bayern Munich.
Helping in that run has been Aubameyang, a summer signing from St Etienne, who is eager to test Arsenal with the blistering pace that is quickly seeing him become one of the Bundesliga's most feared strikers.
"When I was with the Milan youth teams I ran 30 meters in 3.9 seconds, that was official, but I've run it in 3.7 seconds too," Aubameyang told the Guardian.
The Gabon international introduced himself to the Bundesliga in emphatic fashion with a hat-trick on his debut for the club in August. Collectively he has struck five goals in his first nine appearances for Dortmund, and has tentatively warned Arsenal he is yet to step out of first gear.
"I don't think I have reached my top here at Dortmund yet," he continued. "I know my body. There is still more to come."
Dortmund will be without the presence of their manager Klopp on the side-lines for their clash at the Emirates Stadium as he serves the remainder of his two match ban after being sent to the stands following a wild outburst aimed at the fourth official during his side's defeat to Napoli.
But despite his absence, the German backs his side to take all three points against Arsene Wenger's in-form side.
"It's hell not being on the bench but I made a mistake," the Dortmund boss said. "The team, though, can handle it. Of course we can win in London."
