Ducati's Valentino Rossi insists he hasn't opened discussions with any other manufacturers for 2013 and isn't sure what Carmelo Ezpeleta meant by a recent comment.

Omnicorse.it recently quoted the Dorna CEO as saying:

"Valentino next year will be riding a competitive bike, but I [can't] tell you what it is. It is still too early to talk about: in 2013 we will see Rossi fight for the win... again."

Rossi was asked about that comment, which some took to mean the Italian was planning a switch back to Honda or Yamaha, at Assen on Wednesday.

"I think this is only his idea, or maybe he knows more than me [laughs]," GPone.com quotes Rossi as saying.

"I haven't requested a bike from either of those two manufacturers [Honda or Yamaha]. My objective is to make the Ducati competitive and to continue with this team."

Rossi won three MotoGP titles for Honda and four for Yamaha before joining Ducati at the start of 2011, since when he has taken just two podiums.

The only factory 2013 MotoGP seat so far decided is Jorge Lorenzo's Yamaha ride.
