SINGAPORE - Fernando Alonso has made two things clear about his immediate plans for the future: he wants to win, and he wants to win in Formula One.

The two-time world champion's pedigree has been buried in a sub-par McLaren car this year, and with Alonso as yet not committing to any contract for next year, speculation has been mounting about a possible move away from the team or the sport altogether.

"Whatever I do next year is because I want to win. I don't want to be fighting for the top 10 or the top 15," said the Spaniard during a press conference at the Marina Bay street circuit on Thursday (Sep 14).

"There are many options out there but F1 is my first and only priority."

Alonso's frustration has been palpable all season as he lies 15th in the drivers' standings, having taken just 10 points from 12 races.

So starved of winning was Alonso that he gave the Monaco Grand Prix a miss in May to race in the Indy 5000 series.

Meanwhile, Renault driver Jolyon Palmer was putting up a stoic front even as rumours continue to swirl that Toro Rosso's Carlos Sainz is set to replace him.

"I'm just focused on doing the job that I'm doing, so I try not to pay any attention to that sort of thing," said the Briton, who has yet to record a point this season.

"I have a contract and seven more races to do this year. I'll be in Malaysia and I'll be racing to Abu Dhabi."
