The polarizing player let his thoughts about the crowd known.

Teenager João Fonseca completed an incredible five-set comeback match to upset Novak Djokovic at the French Open, handing him his first loss to a teen.

PARIS (AP) — At age 39, Novak Djokovic can still wear opponents down. Even opponents nearly half his age — and in front of a hostile crowd. Djokovic came back from a set down for a 5-7, 7-5, 6-1, 6-4 victory over 22-year-old home player Giovanni Mpetshi Perricard in the first round of the French Open on Sunday in his record 82nd Grand Slam appearance.

Novak Djokovic walked into Roland Garros looking for rhythm, confidence, and another step toward tennis history. Instead, he got a four-set grinder, a fired-up French underdog, and a Paris crowd that sounded more like a soccer stadium after midnight than a tennis court in May.

Novak Djokovic did not hold back as he accused the fans of disrespecting him during the French Open second round match on Wednesday while playing against Frenchman Valentin Royer.

Chatrier, it saw another one of the most historic upsets in the tournament’s history. In a third-round match that stretched for 4 hours and 53 minutes, 19-year-old Brazilian sensation João Fonseca engineered a miraculous comeback from two sets down to defeat 24-time Grand Slam champion Novak Djokovic.
