Barrichello not guaranteed future at Brawn

Even two wins in three races has not been enough for Rubens Barrichello to secure a definite future at the Brawn team.

The British team makes no secret of wanting to keep championship leader Jenson Button on board for 2010, but as for the longest-serving driver in F1 history, chief executive Nick Fry answered at Monza: "We'll see.

"We're very much concentrating on each race now and they are both doing a brilliant job. Let's leave it at that for the moment," he added.

However, team boss Ross Brawn has suggested previously that Button alongside Barrichello, who is 37, is a lineup that would serve the Brackley squad well beyond November's Abu Dhabi finale.

Asked whether there are any reasons to make a change, he answered: "Not really, no. They're both doing a fantastic job."

But Brawn insisted that the driver question for next year is still open.

"It's still to be decided," he added. "We're working on it.

"We've other things we have to sort out and then the drivers will come after that."
