Ross Brawn has stated why Lewis Hamilton can't be compared to Michael Schumacher, the most successful Formula One driver of all time.
Brawn, who worked with various teams as well as his own, has put it down to different eras and the contribution they made to their respective title winning teams.
Brawn was a vital part in engineering Schumacher's success at Ferrari, where he raced for eleven seasons and claimed five titles. Brawn also got him back into F1 with a three year run at Mercedes from 2010-2012.
"He loved driving racing cars. He just adored getting his backside into a racing car at any opportunity he was given. That was a combination that was very difficult for people to beat. He's hugely self-motivated," Brawn told ESPN
"I think he alone raised the standard of fitness for racing drivers by a huge margin when he was racing, and he was a great team player. He was really motivational within the team. So you put all of those elements together and they combine to give you a seven-time world champion."
Brawn went on to speak about how Schumacher built Ferrari to make them a title winning team again.
"I think different eras in the sense that Michael generally had to build a team with Ferrari. He went through that process and Lewis has not done that. Not because he's not capable, because he's never needed to," he explained.
"He certainly contributed a lot to Mercedes but he didn't find a team at quite the same time as Michael found Ferrari in the 1990's. Michael's contribution to the Ferrari team in the late 90's and 2000's was very significant. Clearly somebody for instance, Sebastian Vettel, wants to emulate that."
