Yamaha Racing managing director Lin Jarvis insists there have been no meetings with Spanish telecommunications giant Telefonica, regarding title sponsorship of Yamaha's Factory MotoGP team.

Speaking at a special Yamaha Motorsports presentation after the opening day of 2014 testing at Sepang, Jarvis said:

"There are rumours of Telefonica coming back pretty much since they have left. I am aware of the rumour. At Yamaha we haven't met Telefonica people so I think at this moment it just remains a rumour.

"But if Telefonica would come back then it would be very nice if they came back with us."

While sponsorship of Valentino Rossi and Jorge Lorenzo's team may only be a rumour at this stage, Telefonica will be involved in MotoGP 2014.

The company has reached an agreement with Mediaset Espa?a and Dorna to share Spanish MotoGP broadcasting rights through their subscription platform Movistar TV.

Telecinco will show races nine MotoGP races live with the others as delayed broadcasts, while Movistar TV viewers will see every MotoGP live, including practice and qualifying.

Telefonica and its MoviStar brand won the 2000 500cc crown with Kenny Roberts and Suzuki, before switching to Gresini Honda in 2003, bringing Spanish star Sete Gibernau with them.

Gibernau lost out on the MotoGP crown to Rossi in 2003 and 2004, the year Rossi moved from Honda to Yamaha, with Gresini team-mate Marco Melandri finishing runner-up to Rossi in 2005.

Telefonica abruptly left MotoGP at the end of that season, apparently unhappy to have lost Dani Pedrosa just as its next Spanish star was stepping up to the premier-class.

Pedrosa had honed his racing skills in the MoviStar Activa Cup, run by Alberto Puig, then raced in Telefonica branded teams throughout his stellar 125 and 250cc grand prix career.

However Pedrosa's 2006 factory Honda MotoGP deal meant switching to Repsol colours.

Despite its on track success, Yamaha has been without a title sponsor since Fiat left at the end of 2010.
