Anthony Joshua is now one of the biggest names in boxing - there's little doubt about that.
He takes on Carlos Takam this Saturday at the Principality Stadium in Cardiff, Wales, with all of WBA, IBF and IBO heavyweight titles on the line.
The 28-year-old was originally slated to face Kubrat Pulev, the mandatory challenger to his IBF strap. However, after the Bulgarian pulled out of the bout with a pectoral injury, Takam stepped into the breach.
Joshua is the clear favourite with the bookies to remain unbeaten on Saturday and most pundits share that general consensus.
The Watford-born fighter has a perfect record of 19 fights, 19 victories and 19 knockouts on his CV and his last fight saw him stop Wladimir Klitschko at Wembley.
Welsh boxing legend Joe Calzaghe knows all about boxing at the Principality Stadium. He fought Mikkel Kessler back in 2007 to end a decade of world dominance at super middleweight and he thinks Joshua will enjoy success in Cardiff, too.
"I don't see this Takam lasting more than three or four rounds tops."
However, he also sent out a warning to AJ ahead of the world title fight.
"He (Joshua) has to make sure he's not complacent," said Calzaghe. "You know the ones that are tough and the ones you should be able to beat quite convincingly, but it's their night as well.
"They are going to give everything and might do something that they've never done before. And if you lower yourself a little bit, you're going to get caught."
Joshua has aims of unifying the heavyweight division by the end of 2018 and his promoter Eddie Hearn has suggested that if they can fight WBO champion Joseph Parker in February or March, then a huge summer showdown with Deontay Wilder could well be on the cards.
However, the fact remains that Joshua needs to focus on getting passed Takam first.
Still, Calzaghe thinks AJ's personality will be key in taking the contest seriously: "Judging by his personality, he seems a calm individual. He keeps it real. In every part of the fight, I see all the strengths coming with Joshua."
For all of Joshua's power, Takam has only been stopped once in his 39 fights. He also took Parker the distance prior to the Kiwi becoming WBO champion.
One thing is for sure, Takam will have the guts to trade with AJ.
