Promoter Don King has played down Danny Williams' hopes of a world title shot but backed British heavyweight champion Matt Skelton to shine in the USA.
Don King controls a lot of what goes on at heavyweight
King was underwhelmed by Williams' win over Audley Harrison last weekend.
"I don't think the win can equate to Williams being in the top five or six heavyweights in the world," said King.
"But I think Matt Skelton is a great prospect so we will see what we can do with him. [Skelton's promoter] Frank Warren and I can work together well."
King was at ringside in Berlin to see seven-foot Russian giant Nikolay Valuev dethrone WBA heavyweight champion John Ruiz.
And he has been talking about organising a mega tournament between the four major title holders to revive interest in the top division.
But he does not see Williams as a key player at the weight.
"Williams holds a victory over Mike Tyson but Tyson had diminished quite a bit," said King.
"He won the fight with Audley, but Harrison was not a top heavyweight. He just had a big name in England because he had won at the Olympics."
