After having faced each other 37 times on the ATP Tour as rivals, the legendary duo finally found themselves on the same side of the net as they took on Sam Querrey and Jack Sock from the World team in the alternative format.
Federer and Nadal won the opening set and fans thought it would be plain sailing for the star pairing, but Sock and Querrey roared back to take the second, losing just one game in doing so.
With 35 Grand Slam titles between them, every shot from the Europe partnership was celebrated wildly by the fans in Prague - and on social media.
