Roger Federer still had something surprising in his locker despite stepping out onto court for the last time.

Federer treated fans at the Laver Cup to something they had never seen before when he managed to squeeze a forehand through the net.

At 1-1 in the first set, Federer lunged in and attempted to send a forehand down the line. However, dispute mishitting the ball, it ended up bouncing past opponents Frances Tiafoe and Jack Sock for the winner.

Team Europe were quick to have their say on what had happened.

"It was not meant to be, but my eye was still good!" Federer said to his teammates. I saw that it went through - or it must have!

Rafael Nadal added: "I didn't see it. But the rule should be that if the balls go there then you win the point. For sure!"

Thankfully for Federer’s opponents, the officials used modern technology to determine what had happened. Relying on a replay on the big screen, it showed that the ball went through a tiny gap where the net chord attached to the post.

In the end, Federer and Nadal had the point taken off them. Even though the pair had the point taken off, they could still see the funny side of what had actually happened.

The Swiss even had a joke with the umpire: “But my eye is still good. I saw that it went through."

It is fair to say that the fans were in sheer shock as to what happened during that moment, but still saw the amusing side of the proceedings.

Before the tennis action began, as Federer walked onto the court, the Swiss entered to a huge standing ovation and embraced all Team Europe members.

Even throughout the action, the O2 Arena crowd were always quick to cheer for Roger every time he was involved in the action.

Many were just in sheer awe that they got to see the tennis legend compete one last time following his recent retirement announcement.
