Unbeaten Deontay Wilder came out on top against Bermane Stiverne on Saturday as the American defended his WBC heavyweight title with a first-round knockout.

However, it was the immediate aftermath of the clash which really grabbed the headlines.

After the victory, Wilder called out British giant Anthony Joshua as his next opponent, and the IBF and WBA champion has been biding his time to respond.

"I know I am the best. Are you up for the test?" Wilder asked Joshua.

"I've been waiting on that fight for a long time now. I declare war upon you. Do you accept my challenge?"

With a Joshua-Wilder fight on the cards, footage has circulated the web seemingly putting the latter in a weaker light.

After 39 professional fights, Wilder has had a remarkable career to say the least.

However, it hasn’t always been so plain sailing for the heavyweight.

Back in 2008, Wilder was on the receiving end of a battering from Russian Evgeniy Romanov albeit, in an amateur bout.

Nevertheless, it showed a less superior side to the boxer and one that poses questions as to whether he can actually defeat Joshua should the clash go ahead.

As you can see by skipping to 7:40 into the clip below, Wilder is on the receiving end of a looping overhand right from Romanov before the Russian finished the job off after three more hits to the face sent the American crashing to the deck.

It’s obviously not ideal for Wilder to have that footage circulate the web but on the plus side, it was nine years ago and his career statistics - particularly as an unbeaten professional - have definitely shown a change to his ability.
