Boxing: Lewis warns Froch not to underestimate Ward

Former heavyweight champion Lennox Lewis has warned Carl Froch not to take victory for granted if he gets his wish to fight American Andre Ward.

Froch defended his IBF super-middleweight title and took Mikkel Kessler's WBA belt with a unanimous points decision win over the Dane at London's 02 Arena on Saturday.

Froch has only lost twice in his professional career, but one of those defeats was against Ward and retired British star Lewis thinks his compatriot will have to improve significantly to beat the American.

"He's really going to have to go to camp and fix up some of his technical issues," Lewis told BBC Radio Five's Sportsweek programme on Sunday.

"He cannot fight the same way he fought in this fight.

"Against Andre Ward he has got to be a little bit scared because Andre Ward is a serious hombre and he's coming there to fight and he's looking for that knockout.

"If he sees a chink in your armour in any way he will seize that opportunity."

While Lewis saw reasons for Froch to be concerned despite Saturday's success, he admitted he was impressed with the way the Briton took the fight to Kessler.

"Let me tell you he felt really comfortable in there," Lewis added.

"He basically threw a lot of the boxing out of the door and he was just going in there for a smash-up. He boxed really well, he was in control."

However, Kessler did connect with a powerful punch that landed too easily in the sixth round and that was an area of concern for Lewis.

"There were a couple of sticky moments that I was concerned about but he did very well. He showed he can take a punch," Lewis added.

"I was surprised at Kessler because although he looked like the better boxer he just didn't have the heart for it.

"Froch had the heart and the willingness. He just wanted to show everybody that he's a banger.

"He really dug deep. Even that last round because if I was his trainer I would have told him he had won the fight and he did not need to risk anything.

"But he wanted to risk it and he wanted to go in there and knock Kessler out."
