Valtteri Bottas handed Williams drive

Finland's Valtteri Bottas has attempted to lower expectation levels after being named as the replacement for Bruno Senna in the Williams Formula One team for 2013.

Williams team principal Frank Williams described the 23-year-old as "quite simply one of the most talented young racing drivers I have come across" but Bottas said: "Being successful in the future is my own goal. I have a lot to learn."
