Frank Williams, Team Principal of the AT&T Williams team:
“First, I would like to thank Nico for his hard work this year, and before that in preparing himself for Formula One. We are very proud to have supported him as he secured the Formula 3 and GP2 titles and during his debut in Formula One. At Williams we have for many years tried to bring new talent into the sport, and we are convinced that Nico will go on to great things. We wish him well and hope that our paths will cross again in the future.”

“We recruited Rubens to Williams knowing that he would bring technical expertise, experience and passion. He has delivered everything we could have hoped for this season and we are delighted to confirm that he will drive for us again in 2011.”
