Andy Murray said securing Britain's first Davis Cup win for 79 years was a more emotional experience than winning Grand Slam titles or Olympic gold.
The British number one beat Belgium's David Goffin in straight sets to give them an unassailable 3-1 lead in Ghent.
Murray, 28, won 11 of 12 points during Britain's first successful campaign since 1936.
"It's an amazing feeling. I imagine it will take a few days before it really sinks in," said the Scot.
"I've been pretty upset having lost matches before but I'd say that's probably the most emotional I've been after a win.
