McLaren say new driver Sergio Perez is facing 'hard winter'
Sergio Perez, 22, has recently conducted a fitness test to which McLaren submit all their drivers and it proved he is a long way short of the physical condition of Hamilton and his team-mate Jenson Button.
McLaren say Sergio Perez has to up his game before he joins them in 2013 as Lewis Hamilton's replacement.
Martin Whitmarsh said after Sunday's US Grand Prix: "He has got a lot to learn and we've got a hard winter ahead with him. "I am not worried about him. We have the winter to prepare him," Whitmarsh said.
"He will spend a lot less time in Mexico than he realises at the moment. That means he will be in the simulator, will be with the race engineers, he will be with the strategy people, he will be with the general engineering team, he will turn up considerably fitter and stronger than he is today.
Perez's recent form with his Sauber team has led to widespread questions within Formula 1 as to whether McLaren have made a wise choice. There has been speculation that McLaren, who have to pay for their Mercedes engines for the first time next year, have signed Perez in an attempt to tap into some of his lucrative Mexican sponsorship. But Whitmarsh says this is untrue.
