Birmingham City fan Frankie Gavin endured a difficult night's work as he beat former Blues midfielder Curtis Woodhouse by split decision in Liverpool.
Gavin, 25, once cheered Woodhouse on from the St Andrew's stands before the Yorkshireman eventually retired to pursue his boxing dream.
Admiration has since turned to animosity as the two found themselves on a collision course culminating in tonight's fight and after a sub-par performance, the fleshy Gavin was fortunate to take the win at the Echo Arena.
While Gavin, Britain's only world amateur champion, was obviously the clear favourite, Woodhouse is no soft touch and has proved many of his doubters wrong since switching to boxing by amassing a decent record of 15-2, 10 of his wins early, heading into the fight.
Unbeaten Gavin (10-0, 8KOs), defending his lightly-regarded WBO inter-continental belt, made a poor start and had his face reddened in the first round by Woodhouse's consistent jab.
He improved slightly in the second, landing right hooks to the body, but was still being caught too often for a fighter of his amateur pedigree.
Generally he was struggling and in the third took several clean shots as Woodhouse landed lefts and rights almost at will.
A cutting left hand by Gavin in the fourth was shaken off quickly by Woodhouse and an uppercut with the same hand later in the round was also dealt with well.
The fifth was by far Gavin's best round, finally eluding most of Woodhouse's shots while landing lead rights and strong lefts.
Woodhouse landed a lovely straight right on the button in the eighth but Gavin, having edged the previous two, soaked it up and probably took the round.
Woodhouse was bloodied around the left eye as the scrappy nature of the fight continued with ringside opinion split over who was winning it.
Regardless, Woodhouse was performing brilliantly and in the 10th landed a superb short right which sent Gavin's gumshield flying.
Gavin was cut around the nose and in seriously deep water as even his power shots had little effect.
The final round was equally scrappy and while the verdict could have gone either way, it was Gavin who took it with scores of 117-112 and 116-113 in his favour and 115-114 against him.
