SEPANG, Malaysia (Reuters) - World champion Lewis Hamilton admitted he was 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.

"I find it quite funny," the Briton told reporters at Sepang on Thursday ahead of the Malaysian Grand Prix.

"Also, it's only been one race, so to already have comments after the first race is what I find funny."

Hamilton noted that Horner made few complaints when Red Bull claimed four constructors' titles in a row from 2010, with Sebastian Vettel winning the world title in each season, and said Mercedes had never voiced any displeasure during that period.

Hamilton remains confident that Mercedes will stay ahead of the pack in Malaysia but is wary of the threat posed by his team-mate.

"I think Nico will be quick this weekend and he'll be pushing as hard as he always did last year in qualifying," he added.
