Anthony Joshua and Joseph Parker finally fought in Cardiff on Saturday night - the first time two undefeated champions clashed in the UK.The fight did and didn't live up to expectations as fans were left disappointed by the relatively slow pace and lack of a decisive finish - but it was difficult to deny that these were two elite fighters.It was clear how much Joshua and Parker respected each other, with neither willing to take too many risks out of fear for the others finishing ability.The referee, however, came under heavy scrutiny from the watching public as he consistently forced the two men apart whenever they got close - for some, it completely ruined the fight and prevented any kind of flow.Both were instead forced into a more professional boxing match than the scrappy fight many hoped for, Joshua staying behind his jab and Parker patiently waiting for his openings.The Brit would get the victory in the end - judges scored it 118-110, 118-110 and 119-109 unanimously for Joshua.The champ would then get persistent questions afterwards about WBC title-holder Deontay Wilder - a fight Joshua was eager to say he wanted, much to the excitement of the crowd.But Wilder wasn't the only fighter AJ called out; Tyson Fury also got name dropped.You can see Joshua talking about his next opponent here:

When asked who he wanted next, Joshua was clear about who was on his mind: "Wilder," he said, "or Fury. Either one."

It may have just been one word but it was enough to get fans debating on Twitter, both sides adamant that Saturday's fight showed that their guy had the edge.

Check out some of the reaction below:

It's difficult to say how far away that fight could be - Fury hasn't boxed for a long time and that makes him a strange opponent.

While you'd imagine it would give Joshua a major advantage considering Fury's almost certain ring-rust, it also means the former-champion has little to lose - he's making a comeback, after all, and any loss can be put down to that.

Fury at his best is almost certainly the most dangerous opponent that Joshua could face and, based on the incredible turnout for Saturday's fight, would arguably be the biggest British boxing match ever held.

As for Fury himself, he had a message of his own for Joshua:

"Listen AJ," he said, "please don't fight Wilder because he'll knock you spark out and take my 50 million.

"Let me break you and your little bum."
