Nadal insists Federer Slam record not on his mind

World number one Rafael Nadal insisted Wednesday he isn't focused on matching Roger Federer's record Glam Slam haul at the Australian Open this month.

The 33-year-old last year won the French and US Open titles to move within one of his Swiss rival's record tally of 20.

Federer has sat on top of the all-time list since 2009 when he passed Pete Sampras' benchmark of 14 after winning a five-set thriller over Andy Roddick at Wimbledon.

A Nadal triumph in Melbourne could set the stage for him to set a new landmark at Roland Garros, where he will start hot favourite to add to his 12 French Open titles.

But the Spaniard downplayed the potential historical implications after steering Spain into the ATP Cup quarter-finals.

"I honestly don't think much (about Federer's record)," Nadal said.

"My only goal is to keep playing good tennis, keep enjoying this sport and being happy. And if that happens and I stay healthy then the goal is to keep producing chances in the events that I'm going to play."
