Casey Stoner insists that his Ducati team is working hard to find 'something extra' in his quest to return to the MotoGP victory circle, but laments the reality is likely to be somewhat tougher.

Stoner heads to Motorland Aragon for the inaugural Aragon Grand Prix keen to forget the last two events having retired at Indianapolis and trailed in fifth at Misano.

However, the advent of a new circuit gives Stoner renewed optimism that he can get back onto the podium, even if he admits he still needs to find a solution to improving the feeling of the GP10.

"I'm happy to be going to Aragon. The last two races have been difficult for us and racing at a new track is exciting. We'll go into the weekend with optimism and hope that the track is good fun and well suited to the Ducati, although being realistic we know we face a tough job to find something extra.

"The team and all the engineers are doing a fantastic job so it is a case of giving my maximum and helping come up with something new to improve the feeling with the bike, to get it turning better and find some more grip. More than anything we want to put the last couple of weeks behind us."
