The 35-year-old Italian has made a big impact on his debut season in WSBK with the Alstare Suzuki team, winning his first race and lying third in the championship.

But recent speculation has linked the 2005 champion team with a switch of codes, which would include Biaggi crossing back to Grand Prix racing with them.

The Roman Emperor though, refused to commit to either series when questioned about his future.

"It's funny," said Biaggi. "I think it's [the rumours are] just part of the 'colour' of motorcycling and the important names of motorcycling. Sometime it's me, sometimes it's Rossi, sometimes other people.

"There is always attention, and people want to hear these things. Maybe some of it is true, I don't know. At the moment I am the only one who doesn't know, really! I only want to think about racing."

It has been rumoured that Alstare will switch to Moto GP next season with Corona beer increasing their backing for the team and 1993 World Champion Kevin Schwantz assuming a management role.

Four-time 250cc world champion Biaggi and AMA Superbike champion Ben Spies are the touted riders.
