On Sunday, Novak Djokovic announced that he was bringing Andre Agassi aboard as his coach for the French Open, uniting a pair of two-time US Open champions.

It is hardly the first pairing of US Open men’s singles champions, however. In fact, Djokovic was formerly coached by 1989 Open champ Boris Becker. They overlapped with three-time US Open champion Ivan Lendl coaching 2012 winner Andy Murray – the two reconnected last year – and two-time US Open titlist Stefan Edberg coaching five-time winner Roger Federer.

The recent trend of US Open champions teaming up started in 2006, when five-time winner Jimmy Connors helped 2003 champion Andy Roddick to reach the men’s singles final.

Djokovic said there was no long-term commitment yet with the 1994 and 1999 US Open champion Agassi, but that the two would work together in Paris and then “see what the future brings.”

“Andre is someone that I have tremendous respect for as a person and as a player,” said Djokovic, the defending French Open champion and 2011 and 2015 US Open titlist. "He has been through everything that I'm going through. On the court, he understands the game amazingly well. I am enjoying every conversation that I have with him.”
