McLaren team boss Ron Dennis has paid tribute to Lewis Hamilton and Heikki Kovalainen.
Hamilton has been part of the McLaren family since 1995 and he became Formula One's youngest-ever World Champion last year after narrowly missing out on the F1 crown in 2007.
Dennis insists Hamilton is very much a "feet-on-the-ground guy" and believes the support he receives is key to his success.
"I think the results speak for themselves," he told Autosport. "He is a very balanced feet-on-the-ground guy. He has a phenomenal family, he has had tremendous support and continues to receive tremendous support from his father.
"Obviously also from a lot of people at McLaren who believe in him and believe in Heikki."
Kovailainen joined McLaren at the end of the 2007 season, and Dennis revealed the Finn was "mentally destroyed" when he signed up, but he bounced back strongly at the back end of last season.
"We are very much behind the drivers and when they perform it just makes it very gratifying. It is a privilege to have been part of that, but I get almost as much satisfaction from a situation where Heikki was very much mentally destroyed and not in the best physical condition when he came to McLaren.
"So I look at what he has achieved, with his physical condition and his mental approach, and his ability. It is so easy for his performance to be overshadowed by Lewis, but if you start fuel correcting their qualifying performances, then Heikki did a fantastic job last year and will do a great job this year."
