Based on the rankings system through the pound for pound list, the top ten middleweights in the world have been compiled in the list below.
There's no doubting who takes the number one and two spots ahead of their match-up on September 16, although the eight places following Gennady Golovkin and Canelo Alvarez were tougher to rank.
The likes of Danny Jacobs and David Lemieux have impressed in recent years despite losses to the top dog 'GGG'. whilst former super-welterweight title holder Jermall Charlo moving up has been a welcome addition to the ranks.
1. Gennady Golovkin (3 - 37-0)
The world's premiere middleweight and current holder of four of the five titles on offer. An easy rating.
2. Canelo Alvarez (6 - 49-1-1)
Out to prove his doubters wrong, Canelo has the chance to put and end to the formidable 'GGG' run and confirm himself as the new pound for pound king.
3. Daniel Jacobs (32 - 32-2)
The manner of his close loss to Golovkin cemented Jacobs' position as the third best fighter at the weight.
4. Jermall Charlo (45)
A strong run at 154 pounds has put Charlo in touching distance of a shot at the title.
5. Billy Joe Saunders (NR)
Saunders has a tough defence to negotiate against Avtandil Khurtsidze before the Briton can think about facing the likes of Charlo, Jacobs or the winner of Golovkin v Canelo.
6. David Lemieux (NR - 38-3)
Lemieux is back in form with four victories since losing to Golovkin.
7. Martin Murray (NR - 35-4-1)
Murray's decision to move back to 160 following a disappointing run at super-middleweight cannot be ignored. Murray is a four-time world title challenger and hopes to get one more opportunity soon.
8. Andy Lee (NR - 35-3-1)
Lee contemplated retirement following defeat to Saunders, although the former world champion is once again in contention.
9. Avtandil Khurtsidze (NR - 33-2-2)
Khurtsidze can put the cat amongst the pigeons if he can overthrow Saunders in London on July 8.
10. Sebastian Heiland (NR - 29-4-2)
Since a win over Matthew Macklin over three years ago, the Argentine has been patiently awaiting his chance despite being number one contender for Golovkin.
