Lorenzo rubbishes reports of 2015 Ducati MotoGP deal

Reports in the Spanish media on Thursday suggested that Ducati was poised to make a big-money swoop for the 2010 and '12 world champion at the end of this season.

The stories were swiftly dismissed by Yamaha, and now Lorenzo has underlined that he wants to stay with his current employer.

"When you are fast and winning races all the big factories want you, this is normal," he said.

"I have to clarify that there is no truth in the rumours that there is a contract with another manufacturer and I would like to start negotiating as soon as possible for my future with Yamaha.

"My dream is to retire after my career as a Yamaha rider. If our bike is even better this year then it will be easier..."

Yamaha brought Lorenzo into MotoGP in 2008 after his back-to-back 250cc world titles.

He has previously been pursued by the team's arch-rival Honda but opted to stay put.

The MotoGP rider market is expected to be a hot topic during the 2014 season with all of the current frontrunners out of contract at the end of the year.

Lorenzo's Yamaha team-mate Valentino Rossi has already stated that if his form does not improve within the opening six rounds he is likely to consider retiring.
