Bruno Senna has played down rumours he is set to secure a race seat at Williams for 2012.

It is rumoured the 28-year-old Brazilian, whose late uncle Ayrton was killed at the wheel of a Williams in 1994, will take his sponsor Embratel to the beleaguered British team.

"Despite some rumours, my situation remains the same as before," he insisted on his Facebook page.

"In other words, I am still not confirmed with any team so I'm still battling for a place in F1," added Senna in Portuguese.

Senna debuted for HRT last year, before starting 2011 as reserve driver with Renault (now Lotus). He completed the season in Nick Heidfeld's race seat.

He has scored 2 points in his 26 races to date.
