Senna fears 2011 F1 hopes are fading

HRT has opted for Narain Karthikeyan for one of its seats, and is considering a number of options for his team-mate - but Senna is not one of them.

And with only a few open seats remaining in F1, Senna reckons that things are looking hard for him - especially with teams requiring drivers to bring money.

"The situation is a bit difficult in F1 right now," Senna told Reuters about his F1 plans. "I didn't really have the opportunity to show what I could do last year because of various problems and that didn't help me for this season.

"We are in talks for the few opportunities that are still open but I can't say it's very easy at the moment. Even Nico [Hulkenberg] is struggling to find a competitive seat.

"We may see some talents wasted because of the current situation. I hope I can take any opportunities that are available... you never know."

Senna's former HRT team-mate Karun Chandhok is also looking for opportunities in F1, and has been most strongly linked with a reserve driver role at Team Lotus.
