Alonso will race where he can win in 2018

Fernando Alonso (C) wants a car he can win with

Fernando Alonso says it's too early to talk about next season, particularly because it's such a busy time in his life with his IndyCar debut later this month, and therefore he is not committing himself to anything just yet.

However the Spaniard says Formula 1 will be his priority, but only on the condition that he has a car capable of winning races and should McLaren not show signs of that later this year, he is open to switching teams or even quitting the sport entirely.

"Now it’s a bit of a busy period, with IndyCar, so it is not the time to think if it’s time to find other challenges outside Formula 1, or if Formula 1 will be an opportunity to win the championship, which is my main goal – I’m very open to anything."

Alonso is pleased with the way F1 is headed with the recent rule changes, but that won't be enough to keep him in the sport as he seeks a third title.

"This year the cars are good to drive. Formula 1 is back in a way. I like this Formula 1," he added.

"My intention and my first priority is to race here next year, but not just to race, also to win."

Alonso's contract with McLaren expires at the end of this season and he has therefore given the team, which is struggling alongside partner Honda, an ultimatum if they're to retain him in 2018.

"I’m happy with the team, but we are not winning. If from here to September or October I see an opportunity to win in 2018 I’ll be more than happy to stay, if it’s not the case I will be more than happy to talk to anyone."
