Anthony Joshua faces the biggest test of his career this weekend when he defends his heavyweight titles against Oleksandr Usyk.
The Brit will put his WBA, IBF and WBO straps on the line at Tottenham Hotspur Stadium and victory will put him within touching distances of an undisputed showdown.
The only title to elude him is the WBC crown - belonging to Tyson Fury - who defends it against Deontay Wilder on October 9 in a trilogy installment.
Here's my quick video summary of how I think the fight will go, there's more insight to my tip below the video.
He has fought just twice at heavyweight, beating Chazz Witherspoon and Derek Chisora - the latter being via unanimous decision last year.
Has he impressed since moving up in weight? Not particularly, but has he been forced to showcase his skills which have seen him rated as a Pound for Pound superstar? No.
Some fighters raise their game depending on the level of opposition and when it comes to delivering, Usyk has done it, especially as an away fighter.
He is used to having the odds stacked against him in the WBSS, beating three fighters on away territory.
He has also defeated a Bellew in London so don't expect the atmosphere or occasion to get in the way of Usyk's motive to become heavyweight king.
Usyk is taking on a Joshua who is a fully-fledged heavyweight though and size and power are two vital aspects of the bout. If Joshua goes out all guns blazing then it could be an early night but for this to happen, he has to catch Usyk.
The Ukrainian is an awkward southpaw, something AJ has never experienced before in his 25 fights.
The good news for Joshua is, he won't be up against someone who has power like Klitschko or Andy Ruiz Jr.
Based on his most recent fights, Joshua is evolving and since his devastating defeat to Ruiz in 2019, he has become more calculated perhaps looking up at how Klitschko bounced back from defeat to Lamon Brewster in 2004.
Expect this fight to go the distance and while it will be a close affair, home advantage may play a huge factor when it comes to the scorecards.
Prediction: Joshua on points.
