Final Thoughts: In the wake of the overblown hype of the Mayweather-McGregor extravaganza, this is the showdown boxing purists are hailing as the ‘fight of the year’: undefeated Kazakhstani ‘GGG’ putting his WBA, WBC, IBF and IBO middleweight titles on the line against Mexico’s three-time world champion ‘Canelo’, who at 27 is eight years younger than his opponent. The only loss of big-hitting Canelo’s career was to Floyd Mayweather back in 2013, winning seven fights since – four by knockout. But Golovkin’s punching power is arguably an even bigger threat; GGG’s narrow unanimous decision over Daniel Jacobs in March ended a streak of 23 consecutive wins by knockout. There’s nothing between these fighters in the height or reach departments, while both modern greats are considered to be in their prime. Many pundits contend that Jacobs exposed chinks in Golovkin’s armour, but Alvarez’s style should be more to the champion’s liking and a KO victory to GGG shapes as the most likely result.
