In the fifth set on 11-all 40-all, Roger Federer hit a crazy forehand winner which was initially called out. The Swiss called the Hawk-Eye Challenge, the ball was IN and Djokovic argued with the umpire as the ball was wrongly judged.
After the match, Djokovic praised the Swiss: "I thought most of the match I was on the back foot actually. I was defending. He was dictating the play. I just tried to fight and find a way when it mattered the most, which is what happened. In the most important moments, all three tie-breaks... I found my best game”.
