The intensity that Andy Murray brought to their pre-season training camp in Dubai has shown his protege, Kyle Edmund, how hard he must toil behind the scenes if he is to have a fulfilling and successful life in tennis.

At the age of 20, the Yorkshireman is already a Davis Cup winner after making his debut the same weekend Great Britain won the competition for the first time since 1936. He has been a guest of the Prime Minister's at Downing Street; he has been feted by ESPN analyst John McEnroe as someone with "huge upside"; and he is ranked 102 in the world, having peaked at 99 last season.

There is no danger, though, of Britain's second highest ranked singles player coasting through the next season, or having his progression hijacked by complacency. Even before the trip to the Middle East, Edmund was not a player who might be described as a shirker or slacker. But after being around Murray for more than a week, and "seeing first-hand what it takes to get to the top", he told ESPN how he was dedicated to his tennis like never before.

"I feel as though I'm in a really fortunate position as a 20-year-old, being able to prepare for the season alongside the world No.2. I don't think it gets much better than that," Edmund said before opening his season with victory over Radu Albot to qualify for the Qatar Open.

"The training camp with Andy in Dubai, it wasn't that long, but it was the most intense pre-season block I've ever done. The main thing I've picked up from spending time with him is the work ethic and the intensity. I was mostly hitting with Andy and he's not the world No.2 for no reason - he works so hard and he deserves to be there. He's there because of the hours he puts in and because of the intensity he trains at. Watching him practice at such a high intensity, you can see why he can compete at the highest level for four or five hours, and why he is going so deep into Grand Slams.

"I've seen up close what it takes to get to the top and how hard you need to work. Once you accept that you need to work hard, you're on the right path. It's a long, long journey. I was watching Andy and picking up stuff - you can learn so much from just being around him. Andy is 28 now, and I'm 20, so he has a few years on me. Andy has been playing to that high intensity for many years so he is bit more used to it, and is comfortable doing that, but over the years I'll get more used to it. Hopefully I'll be able to go deeper into slams - that's the ultimate goal."

During their time in the Middle East, Murray was providing Edmund with more than inspiration and motivation; he was also offering precise, technical advice to how to improve his game. "Andy noticed a few things. He was obviously out there working for myself, but he was also passing on bits of advice to my new coach," said Edmund.

That new coach was a Briton, Ryan Jones, with the Dubai camp a trial period. As they got along so well, Edmund said he would be keen to make their player-coach relationship more permanent. "I loved what we were doing on court. It was a great opportunity for us to get together, and to see how it would work together. We also spent some time together off the court, and chatted about things apart from tennis. And then when we were on court, and when it was time to talk about tennis, I thought it went really well," said Edmund, who in the past had worked with Greg Rusedski and James Trotman, and who had recently had some guidance from Leon Smith, the Davis Cup captain.

"Ryan's coming out to Doha and Australia. The next step is for us to work together at a tournament, and for him to watch me play a match. Hopefully he's going to be my coach, but it's like anything, you don't commit to a year or two years if you don't know what's going on. You get a feel for it, and if you're happy, you go for it, and he obviously has to be happy as well."

Edmund's forehand could do some damage on the main tour in 2016. For all the disappointment that Edmund felt immediately after losing on his Davis Cup debut against Belgium's David Goffin -- he took the opening two sets, but then lost to the top-20 opponent in five sets -- he has since had the chance to reflect on what happened in the shed on the end of a tramline in Ghent. What encourages him for the year ahead is that he was able to produce his best tennis in those early stages when under the greatest pressure of his career.

"In the final, I played an opponent of a much higher ranking, and it was obviously a pressure situation, and I think I handled it very well. It's nice to know that I was able to produce some of my best tennis in a pressured environment. It's easy to do that in a relaxed situation, so the fact I could do it when I was under pressure, that gives me confidence for the future, even though I lost the match," he said.

"That whole experience of playing in a final -- with the noise, and the great feeling of representing your country - is something I will always remember. I had never thought that there was any chance that I would be part of a team that won the Davis Cup, so to have done that at the age of 20 is just unbelievable. That's pretty cool. The team achieved something really special," said Edmund, who appreciated the opportunity to walk through the door at 10 Downing Street.

"You see the door the whole time on the news so to go inside was pretty cool. We went inside and spoke to David Cameron in a back room. We spoke about the Davis Cup and also about his tennis. The Prime Minister plays quite a bit of tennis himself so he already has an interest in the sport and it was good to talk to him about it."

Another off-season highlight was stepping on stage at the BBC Sports Personality of the Year awards nights in Belfast, with the Davis Cup players, coaches and staff receiving the team prize.

One more was hearing high praise from McEnroe. And the New Yorker wasn't the only tennis grandee who recently spoke of Edmund's considerable promise. Tim Henman did, too, as did Murray, with those admirers all giving their thoughts at the Tie-Break Tens event in London in December, after Edmund won the competition and the $250,000 prize. "I've never had that before, with people like McEnroe, Andy and Tim saying nice things about me. So when it happens for the first time, you really think about it. That was a great feeling. You don't get that every day. They're not going to give that praise out for the sake of it, so that was really encouraging."
