Jermell Charlo breaks into Ring Magazine’s top 10 list of pound-for-pound boxers after becoming undisputed champion

JERMELL CHARLO has broken into the Ring Magazine's top ten pound-for-pound list.

It comes after the American knocked out Brian Castano, 32, in their rematch to become undisputed light-middleweight champion.

Charlo became only the seventh male fighter to win all of the world titles in the four belt era.

Four of those other names, Olekandr Usyk, Terence Crawford, Canelo Alvarez and Josh Taylor join him in the current pound-for-pound list.

Retired pair Bernard Hopkins, 57, and Jermain Taylor, 43, are the two other historical fighters with all four titles to their name.

For a long time, Canelo, 31, led the way as boxing's No1 but plummeted all the way to sixth after his shock defeat to Dmitry Bivol, 31.

As a result, Russian Bivol found himself placed at No8 and could be in line for a lucrative rematch.

It saw Usyk - the former cruiserweight king - leading the way at No1.

The Ukrainian, 35, is unbeaten as a two-weight world champ and last September dethroned Anthony Joshua, 32.

He is the only heavyweight on the list, with Tyson Fury, 33, nowhere to be seen after retiring following victory over Dillian Whyte, 34.

Terence Crawford, 34, is placed at No2 but as a belt holder in three weights, he believes he should be top dog.

He is set to fight No4 ranked fighter Errol Spence Jr, 32, in a huge undisputed welterweight title decider this year.

The winner will surely be in line for a promotion.

It would see Crawford go to the front of the queue but Spence would overtake Naoya Inoue, 29, the KO king who is at No3.

Mexican super-flyweight champ Juan Francisco Estrada, 32, is in the middle of the pack at No5, one ahead of countryman Canelo.

Vasyl Lomachenko, 34, is still ranked No7 despite losing his lightweight belts to Teofimo Lopez, 24, in 2020.

Lomachenko has won twice since, but George Kambosos, 28, fights Devin Haney, 23, for undisputed lightweight glory in June.

The winner will likely punch their way into the top ten.

Taylor, 31, is still placed ninth despite his controversial win over Jack Caterall, 28, in February.

The Scot now looks set to stay at light-welter, despite teasing a move up, but has been stripped of his WBA belt and sits above Charlo.
