ANDY Murray revealed he stayed up late on Saturday night to watch the boxing before landing the knockout blow which landed Britain the Davis Cup final. Fight fan Murray put his preparation at risk by watching a live stream of Tyson Fury's shock heavyweight victory against Wladimir Klitschko but admitted he needed no added inspiration as he fired Britain to their first victory in the world cup of team tennis for 79 years. The Scot ran out a 6-3, 7-5, 6-3 winner against Belgium's top player David Goffin in just shy of three hours at the Flanders Expo Centre in Ghent to give Britain an unassailable 3-1 lead in the tie. It means that he becomes only the fourth player in the 115-year history of the competition to win all 11 of his rubbers in the calendar year of 2015, and the first since Pete Sampras to win all three decisive rubbers in the showpiece match. It means that only one point in Britain's glory run was not provided by the products of one modest home in Dunblane.

"I did watch the boxing last night," said the 28-year-old, who overcame Ruben Bemelmans on Friday and joined forces with brother Jamie to beat Goffin and Steve Darcis in the doubles. "I was in bed probably by 11:00pm. But I managed to find a stream of the boxing online and I watched it. I always get a bit nervous watching boxing, especially watching heavyweights. It probably wasn't the smartest thing for me to do last night.

"I'm obviously happy to be part of a great weekend of sport," he added. "But I didn't need any inspiration this weekend. I didn't need that from a boxer or anything else. I think that's the case for all of the team. This competition, winning the event for all of us was enough."

The tearful Scot said he had been more emotional in the aftermath of this victory than at any previous point in his career - including becoming the first player from these isles for 77 years to win Wimbledon. He marked the moment in bravura fashion, with a trademark backhand lob, before crumpling to the turf, being mobbed by his team-mates, before breaking off to commiserate with the defeated hosts.

"I probably haven't been as emotional as that after a match that I've won," said Murray. "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. It's incredible that we managed to win this competition. I didn't know that would ever be possible."

The victory completed a remarkable journey under the stewardship of the team's Glaswegian captain Leon Smith, who has taken the side from the brink of relegation to the bottom tier of the competition in his five years in charge. While Smith stressed that this was a team effort, he said that the personal contribution of the World No 2 was up there with any achievement in the sport to date.

"It has to be one of the best achievements of all time," said Smith. "I mean, it's incredible for all of us to watch how he's managed to win that many rubbers, that many wins, especially when you look back at the tie in France and also the Australia match, obviously a lot of fatigue, managed to find a way through."

Smith was remained tight lipped about his future last night amid speculation he could do more coaching of the best prospects north of the border, but Murray has already committed to featuring in the 2016 Davis Cup campaign opener against Japan in Birmingham in March. "For all of the team it's obviously great to have a Davis Cup next to our name," the World No 2 said. "We'll all remember this year for the rest of our lives, regardless of what happens in the rest of any of our careers. Nothing may ever top this now."

There was chat last night of knighthoods, and Murray - who already has an OBE - said the whole team merited an honour. "Look, I think everyone deserves one."
