When it comes to being one of the biggest and best names in the sport of boxing, there are some people who believe that having a good amateur background is the perfect foundation for making it big as a professional.
That has certainly been the case for the Ukrainian cruiserweight king Oleksandr Usyk, who was a dominant force as an amateur boxer and has carried that dominance up to the paid ranks without too much trouble at all.
During his amateur days, Usyk managed to bag himself multiple medals, including Gold medals in the European Championships, the World Championships, and the London 2012 Olympics, before leaving the amateur ranks with a record of 335 wins and only 15 defeats.
Since turning pro back in 2013, Usyk has gone on to win all of his 16 fights, with 12 of them coming by way of knockout.
After beating Tony Bellew on Saturday night, the 31-year-old made it clear that he intended to move up to heavyweight and challenge the best in the world.
Now, though, former world heavyweight title challenger Dillian Whyte has come out to shoot down Usyk, insisting that the Ukrainian does not have what it takes to mix it with the very best boxers in the division.
Whyte said: "Usyk will struggle at heavyweight.
"Heavyweights are bigger and stronger guys and they will manhandle him.
"If I fought him I wouldn't do what Tony Bellew was doing, I'd be charging at him all around the ring. He's not going to drop me with one punch. I would maul him all night long. I would fight him in a very uncomfortable zone for him.
"If it's a big fight and he wants it, he can have it. I'm game. If Usyk wants it he can have it. I'm the 'Can Man', like I say all the time. If you're a top-10 fighter, you can have it.
"I can never see him shock a real heavyweight, maybe his movement to some lazy heavyweight, but as a heavyweight, you close it down, nullify it, and beat him up, rough him up.
"You will out-weight him by two or three stones, so weigh him down, push him around.
"He didn't like a few things Bellew did, like hit him on the side of the head, and he was complaining, so I saw a few signs there that he doesn't like it rough."
It will certainly be interesting to see if Oleksandr Usyk does have what it takes to compete at heavyweight.
