The first edition of the Laver Cup, an exhibition tournament which pits Team World against Team Europe, went down an absolute treat this weekend, thanks in no small part to the efforts of Roger Federer and Rafael Nadal.
The pair continue to defy the norms of biology and seem to be getting better and better with age.
Both men have enjoyed scintillating seasons, politely sharing the Grand Slams between themselves in a year that will live long in the memory for both men and fans alike.
The world was left salivating at the prospect of seeing the two greatest players of all time line up together on the same team, and they did not disappoint.
Though the Laver Cup is considered an exhibition, Nadal and Federer gave it their all, raising the standard and entertaining the fortunate crowd in Prague no end.
Even Nick Kyrgios, who, for once, was quite in the mood for a bit of tennis, could not dampen the spirit of the Federer-Nadal party.
Kyrgios met the Swiss maestro head on and engaged him in a titanic battle.
Nadal, watching from the sides, lived every shot as if he was out on court with his good friend Federer.
The Swiss dipped deep into his repertoire, playing some delightfully sumptuous shots that left Nadal applauding from the sides. However, as the match wore on, the intensity levels soared and Nadal was jumping to his feet with every Federer point.
The final set went deep, the intensity was palpable, and nerves were jangling all over the stadium, while Nadal could barely watch. Eventually, having saved a match point, Federer overcame Kyrgios 11-9 to clinch the title in the most dramatic fashion.
When Kyrgios' return struck the net, Nadal stormed the court, leaping into the arms of his good friend Federer.
They later lifted the trophy together after a weekend that was littered with examples of the two men's friendship.

The fact that two of the most lovable players around are such good friends makes them all the more lovable. Watching them work together this last weekend was such a joy for tennis fans the world over.
One can only hope they have a few more years of entertaining us to come.
