Daniel Ricciardo insists that he is more focused on doing a decent job at this weekend's Brazilian Grand Prix than he is on his long-term future in F1.

The Australian Red Bull prot?g? was parachuted into the struggling HRT outfit at the British Grand Prix, and has shown continuous improvement in the races since then, occasionally getting ahead of veteran team-mate Tonio Liuzzi and the two Virgin entries. He is widely tipped to replace either Sebastien Buemi or Jaime Alguersuari at Toro Rosso in 2012 but, if he knew anything of his destiny, Ricciardo was not letting on at Interlagos.

"Like a few of us, we're not really sure what's happening next year, but I think I'll live for the moment and try to do the best I can this weekend and see what comes from there," he suggested, "Hopefully I'll keep Dr Marko and the guys at Red Bull happy and see what opens up for next year, but it's not really something I'm prioritising at the moment. My mind's set on the weekend."

Despite not knowing where he may be racing next season - current employer HRT last week signed 42-year old Pedro de la Rosa for 2012 - Ricciardo felt that he had given a good account of himself in the ten races he has contested with the Spanish outfit.

"I think it's been not bad," he surmised, "Obviously, it took a while to get the big wheel going, but I think I then gained some momentum and have had some pretty good races since then and some good qualifying. Coming in halfway through the season, it's not the easiest thing to do. There's always going to be things that you're not 100 per cent happy about or things you know you could have done better.

"But there's been a good race along the line and a good qualifying at least, so I know definitely the potential is there. I've just got to try to put it together more often. I think that comes with experience as well as more time in the car. I'm pretty happy, especially if I'm to finish this weekend on a good note, then I'll be satisfied with the last ten or eleven races. I don't know, it's gone bloody quick!"

Despite being with the Red Bull team at Interlagos last season, the Brazilian circuit will be a new one for Ricciardo, but he is not unduly worried by his lack of experience.

"I was here last year playing a reserve role, so had a walk [around the circuit] and I've done a few laps on the simulator so, yeah, I guess I'm coming to the new circuits already a little bit prepared," he confirmed, "Y'know, this is another one the drivers seem to enjoy. It's a short lap here, we go round and round in circles for quite a few laps in Sunday and it's going to be good. I'm looking forward to it. I think like everyone else here, you know, I'm trying to end the season on a high and go home over Christmas and have something to be pleased about."
