 Webber 's two @-@ year contract with Williams ended at the end of 2006 . The team held an option on his services for 2007 which they chose not to take up on its original terms and although Webber had expressed his desire to stay with the team , Williams offered Webber a considerably smaller salary than had been stipulated in the original contract for the option year . Under advice from his manager , Flavio Briatore , Webber then sought another drive . Williams quickly elected to promote current test driver Alexander Wurz to a race seat . Williams team boss Sir Frank Williams stated that he was reluctant to wait for Webber to commit to the team once the option for future years had expired , though he did not blame Webber for waiting to see if there was a seat available at another team .
