Few could argue about the number one choice, who remains undefeated and largely untouched in a 45-fight career. Dominant at welterweight, Floyd is also now a three-time light-middleweight title holder after beating WBC and WBA champion Saul Alvarez. A five-weight world champion in all, 'Money' dropped back down to his regular weight class to see off Robert Guerrero and remain the WBC's champion at 147lb in May and backed that up by nullifying the threat of Canelo using his trademark defensive skills and blinding hand speed. It's hard to see where a genuine threat to his supremacy will come from while he remains in this form, and Marcos Maidana enters their upcoming clash as a huge underdog.

The self-styled 'Son of God' comes in second owing to his domination of a stacked super-middleweight division. Stylish victories over Mikkel Kessler, Arthur Abraham and Carl Froch have seen the American clean up at 168lb, with only his lack of marketability holding him back in the superstar stakes. Chad Dawson - a genuine P4P contender - came down from light-heavy to challenge Ward but hardly won a round, S.O.G putting him down three times before the referee stopped it in the 10th round. Edwin Rodriguez proved no match on Ward's return from an injury hiatus and it will be interesting to see who he is matched with next.

A four-weight world champion (if you count the latest WBO interim' strap), the career of 'Dinamita' will be defined by his quadrilogy with Manny Pacquiao. His sensational one-punch KO of his old rival was one of the most memorable moments of 2013. However, he met his match in Timothy Bradley, who stuck to an intelligent gameplan to out-fox the infamous counter-punching Mexican. However, despite being 40, Marquez may yet have a say at elite level and takes on the rugged Mike Alvarado on May 17 next. A fifth fight with Pacquiao may yet happen.
Popular Pac Man may have been unfortunate to lose a narrow decision to Timothy Bradley but his defeat to arch-rival Juan Manuel Marquez was a little more emphatic, the Filipino knocked out cold. That loss raised the question of whether Pacquiao would ever be able to reach the heights he had a couple of years before, when carrying all before him. But against Brandon Rios, fresh off two wars with Mike Alvarado, Manny showed the hand-speed, movement and moreover the desire was still there as he fought his way to a landslide points win. And despite being written off by many ahead of the Bradley rematch, Pacquiao proved he was as good as ever with an emphatic points win. Claims to still have two good years left in him.

Garcia may not have a huge following beyond the east coast of the America but he is building an enviable CV that needs to be respected. Made his name with that famous knockout victory over Amir Khan, while 2013 saw him defend his two titles successfully against Zab Judah and Lucas Matthysse. Yet while he struggled at times to best a rejuvenated Judah, beating a prime Matthysse will surely gain 'Swift' the international recognition he deserves. A routine defence against Mauricio Herrera in March was closer than expected but he should be more motivated for much bigger assignments later in the year.
Heavyweights, perhaps more than any other, are defined by their era and sadly for 'Dr Steelhammer' his is undeniably a poor one. Since his defence was shored up and his suspect chin protected, Wlad has been imperious in collecting each and every belt going bar the WBC title held by big brother Vitali. Technically gifted with a piston for a jab and a jack-hammer for a right, Klitschko continues to dispatch sub-standard opponents with aplomb. Alexander Povetkin came to fight but the champion used his size and skills to nullify any threat the Russian may have posed. It wasn't pretty, and disappointing that Klitschko was unable to finish it early.

Whatever 'Desert Storm' does in the ring he divides opinion, and little has changed after contrasting wins over Ruslan Provodnikov and Juan Manuel Marquez. Fighting with a point to prove, he won over fight fans by getting off the canvas to beat the heavy-handed Russian. He opted to mix it with Provodnikov despite being hurt in the first two rounds and again in the 12th. The fight of the year candidate saw the American's stock rise but he reverted to type against Marquez, using his skills and intelligence to out-fox the veteran. However, despite entering his rematch with Pacquiao as favourite the American was out-boxed down the stretch and lost his unbeaten record on merit.
'Maravilla' served a lengthy apprenticeship in his native Argentina before stepping up to middleweight, where he has etched his name as a future Hall of Famer. Two fights with Paul Williams was where he finally gained recognition, losing a 12-round war before scoring a vengeful second round knockout in the return with a victory over Kelly Pavlik sandwiched in between for good measure. British pair Darren Barker and Matthew Macklin were both competitive for 11 rounds but it was the victory over Julio Cesar Chavez that secured his legacy. A slight favourite beforehand, Sergio dominated 'Junior' for 11 rounds before being tagged and seriously hurt in the final session. He got through it - somehow - to remain the man to beat at 160lb, and against Martin Murray did just enough in his latest title defence. His big clash with Miguel Cotto in June is likely to be his last.
The two-time Olympic champion had won a world title in only his seventh pro fight but really gained acclaim when he defeated an in-form Nonito Donaire earlier in 2013. The WBO and WBA champion then recorded a shutout win over former bantamweight champ Joseph Agbeko to cement his position as one of the world's best. However, his tricky southpaw style and quiet personality does not turn him on to fans and we may never get the chance to see him be tested against the very best, because he is so good but is not a box office attraction.
Four wins in 2013 have seen 'Superman' storm up the rankings, culminating in a demolition of our own Tony Bellew. However, it was his stunning knockout victory of Chad Dawson that made the boxing world sit up and take notice. A career-long super-middleweight, Stevenson was impatient for a title shot and so stepped up a division to take on Dawson, and promptly put him to sleep with his first left hook of the fight. His clinical power and under-estimated speed and movement meant he was able to take care of former champion Tavoris Cloud, while Bellew also succumbed to the left hand. One of the fighters of 2013.
