"It was a lot of fun".
One commentator on the Tennis Channel said: "That was the first chance Djokovic had to get him and he did". "I loved it. Obviously I wanted to win as much as Roger".
The Swiss ace came from a set down to defeat the big-serving Isner 6-7 (5/7), 7-6 (8/6), 10/7. This was Anderson's first singles win over Djokovic in a decade.
After the game, the duo sat on the bench during the break and had a light time discussing the moment and Federer was quick to say that this is why they don't play doubles as both laughed it off.
"It's not easy playing one of the best players of all time, but what an awesome atmosphere", said Anderson afterwards.
There are no plans for the trophy to go on a Stanley Cup-like tour with the players, but don't be surprised to see players drinking Champagne from it after Sunday's final. "Usually you need matches to get going and play your best in the third round or quarters of a tournament".
The match ended 7-6, 5-7, 10-6.
On Saturday, they played the fourth 10 point tiebreaker of the tournament and it was the first win for Team World.
"The match, well, it was great", said Goffin.
"It's just fantastic, for so many reasons".
"I had to stay really focused and was not easy to finish the match with 7-3 in the super-tiebreak".
Federer's tennis brain is like no other, he has mastered the tactical side of the game and it comes as no surprise that Team Europe's stars have turned to the Swiss Icon for advice during hard times on court.
The Europe captain has sent Federer out for the opening two matches on the final day in Chicago.
