See the best group photos from the Laver Cup lead-up

Players' pre-tournament pictures, like most things in tennis, are usually pretty lonely looking. A player might Instagram a shot of himself practicing, or maybe one with a family member or a friend on tour.

But this year's Laver Cup, with its team atmosphere and picturesque Chicago setting, provided the opportunity for some amazing group photos.

This level of all-star camaraderie can be rivaled only by what happens on the Laver Cup court.

The Laver Cup begins on Friday at 2 p.m. Eastern Time.
