Lleyton Hewitt admits that he is lagging behind in his preparations for the Australian Open due to his commitments as the Aussie Davis Cup captain.
The 34-year-old will face Sam Groth in an exhibition match on Friday as he bids to find form and fitness for the new season, and he insists he has no thoughts about winding down his career just yet.
"I'm so competitive that my main focus is still trying to prepare as well as possible," he said before the exhibition match in Hobart.
"In some ways, my mind has been preoccupied with the other younger Australian boys and trying to work out the best thing for the rest of the Davis Cup squad to try and have a good result over the Australian summer."
Meanwhile, Roger Federer has named Hewitt as one of his most feared opponents during his career – although the Swiss legend was in no doubt about the identity of his greatest rival.
“Rafa [Nadal] for me has been the ultimate challenge,” Federer is quoted as saying in The National AE.
"[Then] people like David Nalbandian and Lleyton Hewitt and Tim Henman – you name it – some guys I struggled to play against."
