Bruno Senna said he’d been aware of Williams’ long-term plans for Valtteri Bottas long before losing his race seat to the team’s test driver.

“Since the beginning of my program with Williams I accepted that I had to share the car with Valtteri Bottas in 15 Fridays as a part of his preparation for a likely debut in 2013,” said Senna.

Senna added: “It has been extremely satisfying to be the teams most regular point scorer and for me to demonstrate my pace in all 20 races.

“I have learned a lot and improved considerably through the season. I have had a relatively short career so far and feel as though I have come a long way in just a few years”.

“I had some notable achievements this year, such as the fastest lap in the Belgian Grand Prix, my favourite track, scoring points on a regular basis and making up many many places through the races.

“Regularly racing in the top ten has certainly been a step forward in my still relatively short career and has allowed me to further sharpen up my race craft. Working with a competitive and supportive engineering team like Williams has left me well prepared for the next step in my career.”

Senna thanked his former team, saying: “I would like to thank the whole team and particularly Frank for giving me the chance of completing my first full season in F1.

“It has been extremely rewarding to develop the Williams FW34 into a consistently competitive race car and cracking the challenge of the Pirelli tyres has been just one of the satisfying points.”

He added he to confirm his future F1 plans soon.
