Anthony Joshua took another big step towards dominating boxing's heavyweight division on Saturday night by claiming the WBO title from Joseph Parker.It means the 28-year-old now just needs the WBC belt, currently held by a certain Deontay Wilder, to complete the set.AJ was deserving of his victory at the Principality Stadium as he kept Parker at arm's length throughout all 12 rounds, using a more intelligent and cautious approach.It wasn't the best fight, though, and many boxing fans believe the referee, Giuseppe Quartarone, was to blame.Quartarone seemed eager to get involved as soon as Joshua and Parker engaged at close range, which disrupted the flow of the bout and stopped Parker in particular from doing any damage.Speaking after the fight, the Kiwi refused to blame the referee for his defeat but did make a few complaints about his lack of English and tendency to step in."When the ref came to the back, he couldn't really speak English," said Parker. "I wanted to work on the inside more. If I was on the inside I could have worked more and thrown more punches."One man who knows something about poor refereeing is Ricky Hatton, who to this day still moans about how his fight with Floyd Mayweather panned out in 2007.Hatton, who was unbeaten at the time, lost in the 10th round but has always insisted the referee didn't help by breaking up the fight every time he found any kind of rhythm.For example, he said in December: "It f***ing winds me up to watch it now, it honestly does. I think they pulled the rug out from under me, I really do."From as early as the first two rounds, I thought 'something isn't right here'. I think if I did have a chance of beating him, the referee put a stop to that."So safe to say Quartarone's performance during Joshua vs Parker reminded Hatton of his own experience, with the Hitman posting a very salty tweet on Sunday morning.

Hatton wrote: "Well done @anthonyfjoshua last night. Doing us proud again. That ref was a disgrace wasn't he? Brought back memories that?"

He's never going to let it go, is he? Hatton still has a point and perhaps with better refereeing his fight with Mayweather - and Joshua's on Saturday - would have ended very differently.
