Federer sets up Djokovic showdown
Federer admitted he was looking to “get him back” following the heartbreaking loss at Wimbledon this year.
The 20-time Grand Slam champion dropped two championship points in his loss to Djokovic in a five-set epic.
“Actually, it’s good for me to play him again, and maybe that all helps to get a chance to get him back,” Federer said following the match.
“Maybe it took me a few days, couple weeks at most, to get over the Wimbledon loss.
“We’ll find out, but I think it’s all flushed away from my side. A lot of water has gone under the bridge since then.”
Only once in his previous 16 appearances at the year-ender has Federer failed to survive the group stage, in 2008.
Djokovic, who is bidding to equal Federer's record of six titles and claim back the world No.1 ranking from Rafael Nadal, faces Thiem later at the O2 Arena.
