No contract talks with Webber yet - Horner

Red Bull's team boss insists talks about extending Mark Webber's contract have not yet begun.

After the Australian driver commandingly won the back-to-back Spanish and Monaco Grands Prix from pole, the energy drink's racing adviser Helmut Marko admitted it is "our desire to continue with Vettel and Webber".

And on Sunday night, team boss Christian Horner was spotted out for dinner with Webber's famous manager Flavio Briatore.

But Horner is quoted by the Sun newspaper as clarifying that no actual negotiations with the 33-year-old world championship leader have yet taken place.

"The team and Mark are very relaxed about the situation," said the Briton.

"He is an important member of the team and he is driving fantastically well. But we have not spoken, and have no real interest in speaking, with any of our drivers.

"When the time is right, we will sit down and look at the paperwork," added Horner.

Webber's contract runs out at the end of the season, while it is believed Sebastian Vettel's current deal - announced last August - was for the 2010 and 2011 seasons.
