Britain has more world champions than ever before, but who are the trainers masterminding the national boxing boom?
After Carl Frampton's momentous victory over Leo Santa Cruz secured the WBA Super featherweight title, the UK boasts no fewer than 14 men in possession of world crowns, with several more surging towards chances to add to the tally.
Those guiding the fighters are not necessarily singing from the same hymn sheet (think back to Shane McGuigan's on-stage shoving match ahead of Frampton v Scott Quigg), but rivalry can inspire trainers as well as boxers. Furthermore, public debate over Britain's finest extends beyond the champions to their mentors.
Here, we profile some of the wise men helping their charges tighten the UK's stranglehold on world boxing...
Joe Gallagher
For more than two months over the New Year, Gallagher trained a trio of world champions in Quigg, Liam Smith and Anthony Crolla. In January, he was named Trainer of the Year by the prestigious Ring Magazine and recently outlined his plans to guide Quigg back to the top, as well as oversee Callum Smith's coronation.
Diligent and outspoken, Gallagher is not everyone's cup of tea but his results speak for themselves. He has an uncompromising approach to fitness but it's his tactical decisions that come under most scrutiny. The Mancunian was widely criticised for Quigg's passive approach in the first half of the Frampton showdown but was then showered with praise for Crolla's dismantling of the dangerous Ismael Barroso.
Dave Coldwell
One of the most likeable men in the sport, Coldwell returned to coaching at Tony Bellew's request in 2014. Prior to that, he had cut down on working in the gym in order to focus on his management and promotional company and he has been involved in almost every aspect of boxing at some stage or other.
All of Coldwell's charges swear by his methods, and the strength of the bonds he forms with his fighters was clear to see in the wild celebrations that followed Bellew's fairytale world title win at Goodison Park in May. He's had his share of success across the pond, too - Jamie McDonnell twice defended his world bantamweight crown against Tomoki Kameda in Texas last year.
Peter Fury
Not many coaches are capable of concocting a plan to nullify a champion as effectively as Tyson Fury nullified Wladimir Klitschko on that famous night in Düsseldorf in November 2015. The Mancunian's performance was a masterclass of discipline as he discouraged the Ukrainian from launching the right-hand assaults that had been the hallmark of an 11-year reign.
The family fortunes are currently hanging squarely on the shoulders of Tyson but in his cousin (and Peter's son) Hughie Fury, the trainer has a second string to his bow that may soon set its sights on Anthony Joshua. With the WBA Super and WBO belts already in their possession, the Furys have a chance to cement a heavyweight dynasty under Peter Fury's guidance.
Tony Sims
The man officially charged with guiding arguably boxing's hottest property; Anthony Joshua. Sims is seen by many as the go-to man in London and judging by Joshua's serene journey to world championship status and Ricky Burns' history-making success in May, it's a reputation deserved.
With two world titles already in the bag, Sims' future as one of the country's leading trainers appears to be secure; he has the likes of Conor Benn, Ohara Davies and John Ryder eager to emulate the success of their colleagues. Sims is reserved with the media and never wastes his words but along with his brother Peter, is held in high regard by those working with him closely.
Shane McGuigan
Perhaps the most promising trainer in the world, 27-year-old McGuigan is younger than some of the famous fighters he trains. In the aftermath of a third defeat at world title level, George Groves turned to McGuigan and is now well on the way towards forcing a fourth shot. Former world champion David Haye is also on the roster and has spoken of McGuigan's work with great enthusiasm.
McGuigan's relationship with his boxers is unusual due to his age, and his good friend Frampton often lives with his trainer during camps. Also in their London gym are youngsters Josh Pritchard, Conrad Cummings and Josh Taylor, who are all unbeaten and turning in performances that suggest it will not be long before McGuigan is celebrating more world titles.
Dominic Ingle
The Ingle gym in Wincobank, Sheffield, is steeped in boxing history. Legendary Irish-born trainer Brendan Ingle carved out the careers of greats such as Herol Graham and Prince Naseem Hamed and his son Dominic has seamlessly picked up the reins.
Ingle's greatest test for some time arrives in September, when the stable's leading light Kell Brook leaps two weight divisions to take on middleweight supremo Gennady Golovkin. Most believe the task that awaits 'The Special One' is far too great but should he upset the odds, his achievement is likely to owe much to a game plan conceived at Ingle headquarters.
Jim McDonnell
When James DeGale controversially lost to Groves in a 2011 British and Commonwealth title fight, whispers suggested the north Londoner would be parting company with trainer McDonnell. He didn't, and the decision has since been fully justified as 'Chunky' regrouped and claimed a world title in May 2015.
Two defences later, and DeGale is yet to be seriously tested by his challengers. However, when the big fights arrive - and arrive they surely will, with the likes of Callum Smith, Badou Jack and Groves all circling - DeGale will be reliant on McDonnell. Also in the gym is young light-heavyweight Jake Ball, who provides DeGale with sparring.
