Britain number one Andy Murray, who scripted history after winning Davis Cup for his country after a long gap of 79 years, said that he had never been as emotional as he was after the win.
The world number two defeated Belgium's David Goffin 6-3 7-5 6-3 to give the visitors an unassailable 3-1 lead in the best-of-five tie.
The 28-year-old said that it was obviously an amazing feeling, adding that it would probably take a few days before it really sinks in, the Guardian reported.
He asserted that he have not been as emotional as he was after the match he won.
The Briton insisted that it was incredible that they managed to win this competition as he did not know that it would ever be possible.
Murray, who gave Britain its tenth team title, has now added Davis Cup to his major titles apart from Wimbledon, the US Open and the Olympic Games.
He has now joined John McEnroe and Mats Wilander as the only men to have an 8-0 singles record in a Davis Cup year, and with the doubles he is only the fourth man to win 11 rubbers in a single year.
