Roger Federer paid an emotional tribute to his home fans after leading Team Europe to the Laver Cup victory.
Federer was one of the pioneers of the competition, held in honor of the great Australian Rod Laver.
And the Swiss played a key role in maintaining the title for the third year in a row.
Taylor Fritz gave Team World an 11-7 lead after beating Dominic Thiem.
But Federer gave Europe a chance by defeating John Isner and sending the match to a decision.
And Alexander Zverev advanced at his side, beating Milos Raonic in a ten-point tiebreaker.
This sparked joyous celebrations when Europe sealed an incredible comeback in Geneva, Switzerland.
Speaking at the post-match ceremony, Federer was invited to speak and greeted Team World and then the crowd for the fantastic atmosphere.
Federer said, “What a weekend it has been.
"The idea of the concept was to try to bring tennis to people.
"Have fun, have an unforgettable weekend and something very special. And I felt it was.
"I can't thank Geneva enough and all the players who fought hard enough.
"I think it was absolutely amazing. Congratulations Team World for an unbelievable fight.
"I can't wait for the next one in Boston. So many emotions. It's been an unbelievable roller coaster.
“This concludes a dream weekend for me to play in Switzerland.
