BMW 'an interesting team' - Rosberg

Nico Rosberg on Thursday would not comment on speculation he has had talks with BMW-Sauber about joining the German squad in 2010.

After four years at Williams, the 23-year-old has also been linked with a switch to McLaren-Mercedes, but for now has delayed his decision about next season amid the sport's political uncertainty.

Asked by reporters at Silverstone what he had to say about the BMW rumours, the German replied: "Nothing at all. All I will say is that it is an interesting team."

He declined to say if talks with the Mario Theissen-led outfit have been held.

The political situation aside, selecting a team for 2010 based on likely performance is problematic. If budgets plummet with an annual cap, Rosberg admits he might be best placed to stay with his current Grove based team.

He pointed out that he genuinely outpaced Ferrari in Turkey two weeks ago, snapped at the heels of Toyota, and has been in the 'Q3' session at every race so far in 2009.

Rosberg also thinks Williams is well placed to prosper if all the teams need to drastically cut costs.

"If the budget cap comes in it will help Williams a lot -- because they're used to a low budget, not that low but somewhere much closer to that level than other teams," said Rosberg.

"So it will be a bit more of a mess for other teams to reduce their budgets by such a large amount, I think," he added.
