The Serb was once the most dominant player around - winning four straight grand slam titles from 2015 to 2016 - but little of that scintillating form was on display when the 12-time grand slam victor was upset by Japanese qualifier Taro Daniel 7-6 (7-3) 4-6 6-1 in the second round in Indian Wells on Sunday.

Team Sky's Michal Kwiatkowski pictured after winning the Tirreno-Adriatico in Italy today. He added: "I tried a couple of stages ago but I came second".
"I mean, I just completely lost rhythm, everything", he said.
Djokovic, who returned to the tournament following his elbow operation was yet to come to his best shape.
Djokovic took six months off after Wimbledon past year and returned at January's Australian Open, where he lost in the fourth round.
Djokovic had four aces but served poorly overall, making four double faults.
Speaking to the media after the match, Djokovic said, "It felt like my first match on tour".
"And I think that, you know, after that tiebreak, I was just a little bit more solid than him".
"But it's not easy to deal with this kind of frustrations after injuries or when you always be the favorite to win a tournament, you come here and you lose in first round". It is still early stages for Novak coming back and the first one after surgery.
