Roger Federer was impressed with both Novak Djokovic and Rafael Nadal during their ATP Cup battle. World No 2 Djokovic toppled his Spanish rival 6-2, 7-6(4) as Serbia won the inaugural tournament in Sydney.
Federer opted against competing at the ATP Cup and Switzerland were consequently pulled out of the tournament.
The 38-year-old cited he wanted to spend more time with his family so did not participate at any events prior to the Australian Open.
When he makes his return in Melbourne he will face a fierce battle with Nadal and Djokovic for the first Grand Slam of the season.
But Federer does not think he should be considered a front runner for the title.
“I’m aware that at 38 I shouldn’t be the favourite, it should be someone probably in their 20s, but the three of us have been able to stay as the favourites which is great for us,” Federer said.
“Both guys are already showing great signs. I was watching a little bit of their ATP Cup match and thought that was a great match.
“Both guys, injury free, are always tough to beat.”
Federer kept himself busy in the off-season as he toured South America alongside young prodigy Alexander Zverev.
The pair played four matches across the region which included setting world record for the most amount of spectators at a tennis match in Mexico.
More recently, the 20-time Grand Slam winner has enjoyed some downtime in Dubai with his family.
But he arrived in Melbourne over the weekend raring to go and fight for his 21st major title.
“I’m aware that at 38 I shouldn’t be the favourite,” Federer said.
“I’ve trained long and hard in the off-season and I didn’t have any setbacks, which is crucial,” Federer said at a promotional event in Melbourne.
