The world motor racing champion Lewis Hamilton says he's amused by Red Bull boss Christian Horner's calls for Formula One to forcibly reduce his Mercedes team's advantage.
Hamilton led a Mercedes one-two ahead of Nico Rosberg in Melbourne a fortnight ago, and such was their dominance - a continuation of last season's supremacy - that Horner suggested measures may be needed to balance out the field.
At a media conference ahead of this weekend's Malaysian Grand Prix, Hamilton said he found Horner's suggestion amusing only one race into the new season.
He says that Red Bull's chief made few complaints when his team won four constructors' titles in a row from 2010, with Sebastian Vettel winning the world title in each of those seasons.
Hamilton remains confident that Mercedes will stay ahead of the pack in Malaysia, but he's wary of the threat posed by his team-mate in an evenly-matched car.
