Jenson Button has refused to rule out switching to Ferrari.
McLaren has an option for 2012 on the British driver that must be activated within the next few weeks.
If the Woking based team lets the option expire, speculation that he is being lined up as the successor to Felipe Massa is certain to intensify.
Asked about Ferrari by the Spanish newspaper AS, 31-year-old Button answered at Silverstone: "Since I was a boy there are three teams I have dreamed about driving for -- McLaren, Williams and Ferrari.
"I fulfilled a dream with Williams at the beginning of my career, and now I am at McLaren.
"I don't know what my future is, but I want to have a car to fight to win races. You never know what will happen in the future, but at the moment I am happy with what I have."
Button said he would not have a problem sharing a team with Fernando Alonso, the double world champion who is regarded as the clear number 1 at Ferrari.
"I am sure that if we were teammates, Fernando and I would have no problem. Alonso is a great driver for who I have great respect, and I think we would do great things together," he said.
Button is more open about his plans to help youngsters start their own F1 careers.
"It's not just (for) after F1, it's during F1," the 2009 world champion told Reuters, revealing his efforts to set up a driver management company with his manager Richard Goddard.
"I think it could be very useful for other people, obviously British kids, but not just them. I think I've got a lot to offer. So it could be very exciting," he added.
