One of the most fascinating aspects of the Laver Cup is seeing the tactics and emotions shown from the benches.
John McEnroe will lead Team World while Bjorn Borg will be on Team Europe's side of the court once again, and we will get to see both tennis greats behind the scenes of the latest edition of the tournament in Chicago.
Who do you play? And how much do you play them?
Even the great Roger Federer is known to get involved with the tactics.
"I always try to be at the service of the team. If I can give some advise then I'm happy to do so. Even more so with the younger guys who are going to go through more emotions and ups and down," said Federer.
