Reigning MotoGP champion Casey Stoner isn't surprised that Valentino Rossi is leaving Ducati and returning to Yamaha next season.
Stoner won Ducati's only MotoGP title in 2007, with Rossi then taking over the Australian's seat at the end of 2010, after Stoner signed for Honda.
But while Stoner's move resulted in a second MotoGP title, Rossi has rarely troubled the podium and has decided to cut his losses and rejoin Yamaha for 2013.
“No [I'm not surprised]. I think, you know, after two years like this it must be difficult, must be a little bit embarrassing,” Stoner said of Rossi's decision.
“He needs to understand if he's competitive again. So going with a bike that he knows he was last fast with and maybe the only opportunity for a different manufacturer on a factory bike.
“It's going to be interesting to see what happens next year. But, no, it's not a strange decision after two seasons like this; it's got to be difficult. So it's better to try and be competitive again on something which you know he's competitive.”
Stoner also used the Indianapolis press conference to 'clarify' a story originating from publications in both the UK and Australia this week, in which Stoner blasted Rossi and his crew chief Jerry Burgess for their inability to improve the Ducati and also accused the seven time MotoGP champion of a 'lack of effort'.
Stoner said the story was not as recent as it appeared, but stood by the comments.
“I want to clarify that,” said Stoner. “That was a lot of context taken out. It was the whole last year and a half. I never did [an] interview and said anything like that last week. I still stand by what I said, but it's been over the last year and a half that it was put together.”
Stoner, third in the 2012 championship with four race wins, will retire from MotoGP at the end of this season.
