Jenson Button believes Nico Rosberg might be in for a surprise when he goes up against his soon-to-be Mercedes team-mate Lewis Hamilton.

The 2008 champion will join Mercedes in January for the 2013 season. Whilst expectations remain low given the pace of the W03, Button says Rosberg might be surprised by what Hamilton can do with a bad car.

"I think he'll probably get a bit of a surprise at his speed," said the 2009 champion. "I know he's been his team-mate in the past but I think he'll be surprised at how Lewis can get performance out of a bad car. I think that will be the biggest thing," he added.

Button, who has enjoyed a friendly relationship with Hamilton, also expects the same of the 'old friends' who competed together in their karting year.

"I think he knows him pretty well. I think Nico knows Lewis better than I do. They've worked together before and I'm sure he knows what to expect."
