The Swiss sealed a historic win in the Australian Open 11 months ago.
But, Basel aside, Federer has struggled in recent weeks.
He was dumped out of the ATP Finals in London by Alexander Zverev after a semi final showdown last week.
The veteran superstar also underwhelmed in Paris.
After his humbling defeat to Zverev, Federer admitted he was still struggling with a wrist injury.
“It should not come as an excuse, but the problem with the hand interrupted my rhythm often in the summer,” he lamented.
“It may influence you in the key moments like against Anderson at Wimbledon.
“I felt the hand for a long time, even here in London a bit.
“I hope it will completely disappear after the holidays, but the positive thing is that I could play till the end and I did not get injured.”
But with injuries hampering his competitiveness, there’s always a chance Federer might call it quits.
In a wide-ranging interview with the Sunday Times Magazine last month, the experienced ace explained that he has concerns about how his body will continue to hold out if he keeps playing.
“What I like about my career is that no one knows what’s going to happen,” he said.
When asked if his new £230m sponsorship deal with Uniqlo means he’ll keep donning his tennis whites until the Tokyo Olympics in 2020, Federer replied: “Not necessarily.
“Two years isn’t a lot in most people’s lives, but for me, there’s a big difference between 37 and 39.
“It depends on how I’m playing, how my body feels.
“I know I’ll still be playing at club level with my kids, but beyond that, who knows?”
Coach Severin Luthi has predicted Federer will retire between 2019 and 2021 – meaning he will not play beyond 40 years old.
“I do not like to speak a lot about his retirement and he does not like to talk about it, because it’s like it approaches faster,” Luthi told Le Temps.
“I can see him playing for at least one to three years more.
“For the Davis Cup, it’s different.
“My contract ends at the end of 2018.
“I want to think about what I want for me.”
If Federer is planning to hang up his tennis racket, he’s being very coy.
The 37-year-old is already planning for next season after his disappointing showing in London.
“As far as tennis is concerned, it would like to find its way back to the net more often,” the Swiss said.
“And of course I want to whip the forehand right again.
“Then there is the condition training with Pierre (Paganini).
“Of course, deciding whether to play sand or not has an impact on the training program.”
Federer is in Dubai over the coming weeks.
His first event of the year will be at the Hopman Cup in Australia.
