BRUNO Senna is determined to secure a place in Formula 1 for next season – although Renault team principal Eric Boullier is unable to make any promises it will be with the Enstone-based outfit.

Heading into tomorrow’s race in Singapore, he concedes to amazing himself with what he has so far achieved.

Since replacing Nick Heidfeld ahead of last month’s Belgian Grand Prix, the 27-year-old Brazilian has made a positive start.

At Spa, Senna qualified a superb seventh, although he undid his good work by crashing into Toro Rosso’s Jaime Alguersuari at the first corner La Source hairpin seconds after the start.

Then at Monza in the Italian Grand Prix on Sunday, September 11, he scored his first points in F1 by coming home eighth.

So far, Senna has justified his promotion from reserve and proved Boullier was right to place his faith in him, and for the remaining six races.

As for 2012, that is a different matter as Renault teammate Vitaly Petrov is contracted, while the hope of many is that Robert Kubica is able to return as he continues to recover from his rallying accident in February.

Senna said: “The best way for me to be racing next year is with the results on the track.

“The objective is to keep having strong results and fix my place in Formula 1, and the key to that is to keep improving and learning.”

Boullier claimed it was “too early” to make a call on Senna’s future.

He then threw a curveball by seemingly suggesting Petrov is far from safe.

The Frenchman added: “You have contracts, but there are some exit clauses for every party.”

Meanwhile, runaway leader Sebastian Vettel could retain his title in Singapore this weekend.
