Rossi plays down latest F1 switch reports

Valentino Rossi insists he is not set to switch to Formula One.

The multiple and reigning MotoGP champion, whose Yamaha contract ends this year, is back in the F1 headlines after a two day test in a 2008-spec Ferrari.

On Thursday at the Circuit de Catalunya, with his father and Felipe Massa in the garage, 30-year-old Rossi lapped even quicker than the fastest time during the 2009 Spanish Grand Prix, despite being fitted with GP2 slicks.

But he told the El Periodico newspaper: "When I could come to F1, I will be too old. There are wonderful drivers there. I'm fine in my world, which is bikes.

"This is just a diversion, some fun, and I am grateful to everybody for the opportunity," said Rossi.

After reports that Ferrari would like to field a third car in F1 for Rossi, the Italian told Spain's AS newspaper that the proposal "is fun, but not feasible".

"Tomorrow I am a MotoGP rider again," he insisted.
