Tasmania's international coach David Macpherson continues to be in high demand on the world tennis circuit.
Macpherson, 54, will once again be part of the USA Davis Cup team to contest the prestigious event in Europe, later this month.
It will be the eighth time Macpherson has filled the role of doubles coach for the USA, with his success rate at 6-1, all with Bob and Mike Bryan.
Away from Davis Cup, Macpherson coached the famous American twins for 12 years, with their career netting them 16 Grand Slam titles, 119 ATP tournament victories plus gold at the London Olympics.
"I don't think any pair in the future will seriously challenge Bob and Mike's record,'' Macpherson said.
With the Bryans now retired, Macpherson is in his fourth year coaching American singles player John Isner, who is also a member of the 2021 US Davis Cup team.
Under the new Davis Cup format, there are only two singles plus the one doubles played, all best-of- three sets, whereas traditionally, there had been four singles matches plus the doubles, all best-of-five sets.
"The doubles is now played last, so if the singles result is one-all, it's going to be a real pressure-cooker situation for the doubles players and coaches," Macpherson said.
"I think the players and fans will adjust to the new format which is played over two weeks in the one region, rather than, in the past, having matches played throughout the year in a range of countries where the local crowds could range from biased to outright hostile."
The former left-handed doubles specialist won 16 ATP titles and reached a world doubles ranking of 11 during his career, but it is as a coach where the former Launcestonian has earned the highest respect of his peers.
So much so that, in 2014, Switzerland borrowed Macpherson from the Bryans to be their doubles coach for the Davis Cup final against France where he helped Roger Federer and Stan Wawrinka to a straight-sets win.
In 2020, Macpherson was chosen to be non-playing captain for the USA team in the initial ATP Cup held in Australia.
"This was a totally different challenge for me. With normal coaching, you give your last-minute pep talk before the match and that's all you can do. But as captain, I was allowed to sit courtside and talk to the players on the changeovers,'' he said.
"Players can react differently to advice from the coach during the match. If they are playing well and winning, they are usually in a good frame of mind, and receptive to any advice but if they are being outplayed and losing, they can sometimes be frustrated and hard to talk to.
"But I really enjoyed that experience."
Based in Florida Macpherson said he always looks forward to coming back to Australia to see family.
