As expected, Pastor Maldonado and Valtteri Bottas have been confirmed by the Williams F1 Team for the 2013 F1 season, leaving Bruno Senna on the sidelines.

Maldonado has been with the Grove-based outfit now since 2011, and his place was never really thought to be in doubt given the massive dowry his presence brings in.

Furthermore while he was been involved in a number of incidents again this year, his winning performance in Spain certainly showed on his day he is as good as anyone.

Bottas meanwhile has been a Williams test driver since 2010 and this year the 2011 GP3 champion took part in 15 Friday free practice one sessions, impressing with his pace and maturity.

Williams founder and team principal, Sir Frank Williams reckons Maldonado and Bottas will make a formidable pair.

"In Pastor and Valtteri we have two of the most exciting talents in motor racing and I am especially excited about what 2013 can bring for Williams," he commented. "Pastor has always demonstrated remarkable pace and this year has seen him mature as a racing driver. Valtteri is quite simply one of the most talented young racing drivers I have come across and we expect great things from him in the future."

As for Senna, Williams have thanked the Brazilian for his efforts in 2012 and while he may not have won a race like Maldonado, he was the more consistent points' scorer.

Indeed he managed ten top-ten finishes over the season compared to the five of Maldonado. Maldonado, however, finished ahead in the standings, with 45 points to Senna's 31.

"I would also like to take this opportunity to thank our departing driver Bruno Senna for his hard work over the past year and wish him the best of luck going forward," Sir Frank added.
