On Thursday, Novak will share the court with his old friend and rival Andy Murray, setting the practice match on the Margaret Court Arena that will be open to the public.
"Wimbledon is where I would like to stop playing, but I am not certain I am able to do that", Murray said, per Fraser.
All the active grand slam winners in the men's game are over 30 and one of the most intriguing storylines will be whether the new generation can finally break the stranglehold.
After barely surviving a practice session with Novak Djokovic yesterday, Murray had to be excused early in his interview when he broke down in tears when asked about his fitness.
The three-time Grand Slam champion was driven to tears as he made the announcement to a room of journalists and revealed that the extent of his pain means he can not put socks on without struggling. "I've tried pretty much everything that I could to get it right and that hasn't worked".
But he conceded there was a chance he would not make it beyond the Australian Open. "I'm not certain I can play through the pain for an other four five months".
The global outpour of support for Djokovic was immediate with fans and legends alike praising the Scotsman. "I like to play attacking tennis, so I've come full circle".
Federer's first-round test comes in the shape of Istomin, an Uzbek whom Federer has defeated in each of their six meetings, and they are in the same quarter of the draw as Andy Murray, who is unseeded and meets Spaniard Roberto Bautista Agut first up.
"I can play with limitations".
Even if he decides to retire tomorrow, Murray will go down as one of the best players of this generation.
Murray, who will turn 32 before this summer's Wimbledon, won the event in 2013 and 2016.
"I spoke to my team and I told that I can't keep doing this, that I needed to have an end point because (I was) just playing with no idea when the pain was going to stop", he said.
