Jenson Button might not be the only McLaren driver on the move.
Although set to stay at the British team next season, in recent days the 2009 world champion has been linked with a move to Ferrari for 2013.
Red Bull team boss Christian Horner, meanwhile, has hinted that - with Mark Webber only confirmed for 2012 - he might be interested in Button or his teammate Lewis Hamilton for the future.
"Both (Button and Hamilton) are out of contract at the end of next year, but they are McLaren drivers so it's not for us to get involved," The Sun quotes Horner as saying.
"But both are phenomenal drivers."
Horner acknowledged that it is Button, 31, who is in better form at present.
"It has been a poor spell for Lewis," he said, "but ... for Jenson Button you can see a driver at ease with himself -- and his driving reflects that."
