Schumacher ready to flex Brawn at Mercedes

Seven-time world champion says he has nothing to prove as new season nears

Brawn was in Schumacher's pits for all seven of his world title wins - two at Benetton and five at Ferrari - and Brawn's involvement at Mercedes was a significant factor in enticing Schumacher back to Formula One.
