With the AT&T Williams team preparing for this weekends Adu Dhabi Grand Prix Williams boss Sir Frank Williams took the time out to discuss the teams plans for the 2010 season, in particular the fact that the Williams team will be using Cosworth engines after having split from their current engine supplier Toyota. Williams also announced that the team would be announcing their 2010 driver line-up on Monday, after this Sunday's race.

In regard to the move back to Cosworth engines for 2010 Williams, in an interview for the Gulf Times newspaper. said that the team was taking a  "more private and independent" route in 2010. "We've finished our contract with Toyota and we've moved on to a British engine manufacturer Cosworth with whom we have won many world championships in the past.

"They are 50 miles away from Williams which is very convenient. Besides we also like our independence. We will be not under the influence, not that Toyota ever bossed around, but we've just gone a private and independent route."

"Our performance needs to improve. We staggered in the second half of the 2009 season. It's fundamental that the car is not fast enough, but from what I've seen we should have been a little more competitive.

As for the driver announcement Williams added: "So we will announce our drivers for next season on Monday. [Nico Rosberg] will be leaving and we just thought it was quite a long time.

There are a few things going on at Williams for next season, with our engines, so we thought we can do better. Nico is German and Mercedes need at least one German driver to sit before their engine."

As for who will drive for the Williams team in 2010 it is still believed that Rubens Barrichello will join the team with GP2 Series champion Nico Hulkenberg being brought in to replace Kazuki Nakajima.
