Senna downplays rumours

The Brazilian raced with the Renault team in the second half of the 2011 season, but the squad has hired Kimi Raikkonen and Romain Grosjean to race with it during 2012.

Senna has been linked recently with the second racing seat at the Williams team, the Grove squad yet to announce who will partner Pastor Maldonado.

Senna, Rubens Barrichello and Adrian Sutil are believed to be in the running.

Despite the speculation, the Brazilian said his situation has not changed.

"Despite some rumours, my situation remains the same as before," Senna wrote on his Facebook page. "I'm still not confirmed with any team and still battling for a place in F1. Let's keep fighting!"

Senna admitted at the end of last year that he would be ready to take a reserve-driver role if it meant he could run in free practice.

"To take a third-driver place it would have to be a similar type of role to what certain people had this year with driving on Fridays," Senna said back in December.

"That allows you to be active and do something relevant with the team. It would have to be with the right team, but it could be an option."
