Steve Collins expects Carl Froch to fight Julio Cesar Chavez junior next after his devastating eight-round stoppage of George Groves.
Collins, the World Boxing Organisation's former super-middleweight champion who retired in 1997 after beating the likes of Nigel Benn and Chris Eubank twice, was hugely impressed by Nottingham's Froch at Wembley.
Froch easily defended his International Boxing Federation and World Boxing Association super-middleweight belts in front of 80,000 fans in London and Collins told Sky Sports News: "There's no disrespect being caught clean by Carl Froch, being stopped in a fight.
"He can put anyone over if he lands that shot. Rocky Marciano was put flat on his face and he was the greatest fighter of all time. If he can understand that and get his confidence back I still think we haven't seen the best of George Groves."
James DeGale was equally impressive in his demolition of American Brandon Gonzales in four rounds on the undercard to become Froch's mandatory challenger for the IBF belt.
Froch turns 37 next month and Collins predicted he would take a big-money pay-per-view fight against Mexico's Chavez jnr in Las Vegas and snub DeGale for now.
He added: "I don't think (DeGale's) the fight he should take because it's a dangerous fight he could lose it but there's other fights out there with a lot more money involved.
"He's at the end of his career, he's fought everybody, beaten everybody and he wants to get the big payday before he hangs up his gloves.
"If he's going to fight anybody he might as well go where the money is. The money's not with DeGale right now, he wants somebody on the world stage for that big payday. I think the fight for him is against Chavez."
Collins gave encouragement to another Londoner, Groves though, tipping him to go on and be a world super-middleweight champion one day.
He said: "He's definitely got the ability and the tools, it's how he gets over this loss and how he handles it.
"Some of the best fighters in the world have been knocked out and come back (as) great champions. If he can realise and accept that, I still think we haven't seen the best of George Groves and he's still improving."
