During Novak Djokovic's clash against Team World's Frances Tiafoe, the one who teamed with Jack Sock to beat Federer and Nadal in Roger's retirement match, the Swiss asked Djokovic if he needed water as he observed he was running out of it.
Djokovic answered: "Yes, some water, please." Federer then brought the former world number one two bottles of water. The Serbian thanked the Swiss Maestro. Watch the video below.
Eurosport captioned the video: "'Need water, you okay?' Nice Guy, Roger Federer" Commenting about Djokovic's performance over Frances Tiafoe, Federer said: "Such control from the baseline, it's great to see after so many months off. Keep it up!"
