After all the hype and psychological warfare, and a build up that has not just captured the attention of the boxing nation, but the sporting world, 36 year-old Carl Froch eventually defended his WBA and IBF super-middleweight titles in Round 8 against challenger George Groves, on Saturday night.

A superb combination of shots late in the eighth round was enough to finally give him the victory that after he described as the 'best boxing moment of [his] career'. He feinted with a left that did nothing but distract Groves, forcing him to take his eyes momentarily from Froch's other hand. Those few seconds were all he needed to land a vicious right hook, sending Groves tumbling to the ground, his legs giving way beneath him. It was a ferocious shot to separate the two fighters in what had, as expected, up until that point been a close fight.

As a sell-out 80,000 crowd roared Groves' spectacular, London 2012-esque open-top bus entrance, and booed Froch as he entered the arena, the anticipation had reached fever pitch. Months of speculation and tense press conferences; the controversy surrounding these two warriors' first fight was the reason this event had happened in the first place. There was unfinished businesss after the referee controversially called an end to the original fight in Round 9, with all three judges having Groves leading on points.

This time, there were no questions about the decision. To his credit, Groves incredibly, instinctively, fought to get back to his feet after taking a brutal hit - but it was too late. The referee rightly called an end to the fight, and once again the fight had finished by KO - once more in Froch's favour, but this time perhaps in less controversial circumstances. Despite this, Groves lamented: ' I just feel like I've let myself down", and he had a point in a fight where after eight rounds, the fight still seemed in the balance.

For the most part, it was a tense, tactical fight that seemed too difficult to call. The two were evenly matched, but in the end Froch proved himself to be the champion that he is; a moment of brilliance in a fight where the world was watching. In that end, Groves' promise to finish Froch with a left-hander was nothing but empty talk. Instead, it was the exact opposite that gave Froch, in his glittering and successful career, one of his greatest ever moments.
