ESPN's British pound-for-pound rankings, featuring Kell Brook, Amir Khan and Anthony Joshua

1. Kell Brook (35-0, 24 KOs)

With the recent retirement of super-middleweight Carl Froch, there is a new No.1 in the British pound-for-pound rankings. The Sheffield welterweight is in the form of his life after registering two stoppage wins in defence of his IBF world title this year. Brook's career looked in doubt after being stabbed while on holiday a year ago but showed no ill effects to see off Jo Jo Dan (4 TKO) and Frankie Gavin (6 TKO) in his home city. He wants to fight Amir Khan but will have to wait until next year at least for the chance to end any arguing over who is Britain's pound-for-pound king. Brook edges it for now via a split decision thanks to his recent form and world champion status.

2. Amir Khan (31-3, 19 KOs)

It has been a disappointing year for Khan so far in that he has missed out on fighting Floyd Mayweather Jr yet again and he also failed to sparkle in his only bout this year. Bolton's former world light-welterweight champion stepped up a division and looked good in two welterweight fights last year, but was less convincing against Chris Algieri in May. Khan beat Algieri on points, but misses out on top spot in our rankings as he does not hold a world welterweight title like Brook, who has looked more impressive this year. If Khan does fight Brook in 2016, it will be the first time he has fought in the UK for three years. But Khan has been linked with a fight against American Keith Thurman next which will see Khan's stock rise or fall. Beat Thurman, or better still Manny Pacquiao, then Khan will leap above Brook in the British P4P rankings before they hammer out a deal to fight each other.

3. James DeGale (21-1, 14 KOs)

Becoming Britain's first Olympic gold medallist to win a world title was a fine achievement in itself, but to do it in America against an American was also mightily impressive. DeGale maintained his improved form since May 2014 by capturing the vacant IBF super-middleweight title with a unanimous points win over Andre Dirrell in Boston three months ago. Signing with powerful American manager Al Haymon may see DeGale box more in the States although a mass-appeal rematch with fellow Londoner George Groves looms sometime in the next 18 months, especially if Groves wins a different version of the world title next month. If DeGale can beat American Andre Ward in a world title unification clash, he will also have a good case to be regarded as Britain's P4P No.1.

4. Carl Frampton (21-0, 14 KOs) & Scott Quigg (31-0-2, 23 KOs)

It might be a bit of a cop-out to put these two rival world super-bantamweight champions at No.4 together, but it is so hard to separate them. Frampton blasted away Chris Avalos in February and then looked the better bet over Quigg, but the Belfast boxer was twice decked in the first round by Alejandro Gonzalez Jr before triumphing on points in America last month. On the same night at the same time in Manchester last month, Quigg dispatched Spain's former champion Kiko Martinez in two rounds (Frampton was taken to points by Martinez last September, and stopped him in nine rounds in 2013). Based on their previous performances then, you would have to favour Quigg ever so slightly. Frampton still remains above Quigg in most rankings due to his possession of the IBF title, while Quigg holds the WBA regular title (with Cuban Guillermo Rigondeaux the WBA super champion). Until a deal can be reached for the pair to meet in a world title unification clash, a judgement on where they stand in the P4P rankings is always going to lead to arguments. But if Quigg beats former champion Nonito Donaire in his next fight, he can claim to be in the ascendency.

5. Lee Selby (21-1, 8 KOs)

After such an eye-catching display to win a world title, Selby may emerge as one of Britain's most popular fighters over the next 12 months. The Welshman's eighth round IBF title-winning display over Evgeny Gradovich showcased his silky skills while a documentary on his life and career on BBC3 has also helped raise his profile. Selby, 28, has benefited from training in the States as well as back home in Newport and Bristol and the Gradovich win was the best of his career. But slick Selby will have to continue his improvement if he is to dominate the featherweight division on the world stage and move up the British P4P rankings. Half a dozen fighters still appear above Selby in global featherweight rankings in what is one of boxing's hottest divisions featuring the likes of Vasyl Lomachenko, Nicholas Walters, Gary Russell Jr and Abner Mares.

6. Tyson Fury (24-0, 18 KOs)

The Manchester heavyweight kept busy with a routine stoppage of Christian Hammer early this year and deserves his shot at world No.1 Wladimir Klitschko on October 24. Only American Deontay Wilder - the WBC champion - and arguably Russian Alexander Povetkin can claim a higher ranking globally than the Briton in heavyweight listings. Fury will have a three-inch height advantage over IBF-WBO-WBA world champion Klitschko, who is 13 years older. However, the Ukrainian has shown no sign of erosion in recent defences. Pulling off the upset in Dusseldorf would see Fury shoot into the top three of our British P4P rankings.

7. Jamie McDonnell (26-2-1, 12 KOs)

Doncaster's WBA world bantamweight champion recovered from a third round knockdown to unanimously out-point Japan's Tomoki Kameda in Texas last May. Beating Kameda, a former world champion in America, was a fine achievement, but other British boxers have received more attention than McDonnell this year. A rematch with Kameda in Britain, a fight with Bristol's IBF interim champion Lee Haskins or a world title unification fight would raise McDonnell's profile and P4P ranking. Stepping up to super-bantamweight to take on Scott Quigg may also tempt McDonnell in the next 12 months.

8. George Groves (21-2, 16 KOs)

The Londoner has had two wins since his two stoppage losses to Carl Froch and fights for a world title when he challenges US-based Swede Badou Jack, expected to be on September 12. Groves has been training with middleweight No.1 Gennady Golovkin to get ready for Jack. Victory will match the world title success on American soil of his rival James DeGale in May and set up the prospect of the pair meeting in a world title unification fight next year, but defeat could be costly for Groves.

9. Billy Joe Saunders (22-0, 12 KOs)

The Hatfield middleweight challenges Ireland's Andy Lee for the WBO world title in Limerick on September 19 after a quiet first half to 2015. Saunders defeated British rival Chris Eubank Jr in November to secure a shot at the WBO crown and has since registered a stoppage win over journeyman Yoann Bloyer last month. After winning European, British and Commonwealth titles, Saunders is due his shot at Lee, but will start underdog.

10. Anthony Joshua (13-0, 13 KOs)

The 2012 Olympic gold medallist continues to make stunning progress in the paid ranks. All 13 opponents have crumbled within three rounds and the WBC governing body has even ranked Joshua as No.2 challenger for their world title, held by American Deontay Wilder. But it is for the Commonwealth title that the north Londoner challenges next, against Scotsman Gary Cornish on September 12. World No.1 Wladimir Klitschko recently hailed Joshua as the most promising boxer he has seen "in 25 years". His knockouts and potential are generating excitement but he is still only 25 and has yet to be in a tough fight. Despite his inexperience, Joshua sneaks into our top 10.

Closing in on top 10: Anthony Crolla, Lee Haskins, Tony Bellew, Ricky Burns
