Anthony Joshua has no choice but to take Andy Ruiz Jr. seriously this time around. The rematch takes place on Saturday in Saudi Arabia as the 2012 Olympic champion battles to win back his belts. AJ is seeking redemption following his shock defeat in June. However, clips of Ruiz Jr. that have done the rounds in the build-up suggest he is in better shape than ever. The Mexican-American has never been knocked out in his professional career and after upsetting the odds in such dramatic fashion six months ago, he has every reason to go into the second instalment full of confidence. 

The current world champion was in buoyant mood at their final press conference ahead of the fight, which took place on Wednesday afternoon.

As the two heavyweights faced off, a heckler in the crowd shouted "two-time", to which Ruiz Jr. added "and still!" without breaking eye contact. 

Joshua remained perfectly silent, but members of his party began to back him up by countering: "And the new!" 

It's still strange to think of Joshua as a challenger, but that's exactly the role he'll have to play this weekend.

The 30-year-old has made far fewer media appearances compared to his commitments pre-Madison Square Garden after he complained of being burned out. 

To many, that just sounded like a feeble excuse but there was no denying he looked burdened even before the first-round bell had rung. 

Perhaps that explains his more subdued approach since his humbling. 

And there remains an element of frustration about the rematch in the Joshua camp.

While it was AJ, of course, who triggered the rematch clause in the original deal, he is still left wondering what might have been if Jarrell Miller had never failed those drugs tests and the fight he had planned for went ahead. 

His stock has fallen dramatically as a result - but if the face-off is anything to go by, Joshua is planning to do his talking inside the ring.
