McLaren will find it tough to take on Renault and Red Bull in F1

Mansell, speaking in an interview with Motorsport.tv at Autosport International, hopes Renault is fair in its supply and does not favour one team over the others.

"It's going to be tough, but hopefully they will be able to get very close and hopefully Renault will be very fair with the supplying of engines," he said when asked how he expects McLaren to stack up against the other Renault-powered teams.

"Obviously, Mercedes don't want to supply them because they don't want them as competitors.

"The hardest thing in F1 is to get a level playing field.

"We need a better level playing field, we need 26 cars on the grid and we need not to be able to spend fortunes to try and bend the regulations."

Mansell also reflects on his rivalry with Ayrton Senna, the spectacle of Autosport International and his golfing prowess.

Mansell was just one of the many big names interviewed by Motorsport.tv during Autosport International.

Gil de Ferran, winner of the 2003 Indianapolis 500, spoke about his career and his experience of working with Fernando Alonso at The Brickyard last year.

World Rally Champion Sebastien Ogier also appeared to look ahead to the new season, where he will try to defend his crown with M-Sport.

Jamie Green offered an insight into his long and successful DTM career, which has taken in spells with Mercedes and Audi since he joined the grid in 2005.
