'Ecstatic' Senna aiming for top 10

Bruno Senna feels "ecstatic" after signing to drive for Williams for the 2012 season and reveals he is aiming to "be in the top 10 every race and build up from there" with his new team.

The Brazilian has taken the place on the grid of Formula 1's most experienced driver, Rubens Barrichello, and believes his countryman has been "very unfortunate" to lose his place.

In signing for Williams, Senna joins the team his legendary late uncle Ayrton drove for when he died in a crash at Imola in 1994, but says his family are delighted for him to compete for the Grove-based outfit in 2012.
