Jenson Button: 'Lewis Hamilton will surprise Nico Rosberg'

Jenson Button has said that Nico Rosberg will be surprised by his new Mercedes teammate Lewis Hamilton.

The 2008 Formula 1 world champion is moving from McLaren to Mercedes for the 2013 season.

Button told Autosport.com: "I think he'll probably get a bit of a surprise. I know he's been his teammate in the past, but I think he'll be surprised at how Lewis can get performance out of a bad car.

"It's been a good three years and it's amazing how quick those three years have gone by. It's been a good partnership.

"We've had quite a bit of fun in terms of racing over those three years."

Sergio Perez will replace Hamilton at McLaren.
