Carl Froch did not hold back in his brutal assessment of Amir Khan's latest defeat to Kell Brook at the Manchester Arena on Saturday night.

Khan was stopped after six rounds by Brook in Manchester as he looked like a shadow of his former self.

And Froch, who was on commentary duties for Sky Sports, felt Khan's weak chin was the decisive factor on the night.

The British boxing legend also admitted that he didn't expect it to be as one-sided as it was.

Froch, 44, told iFL TV: "It was good, it was a good fight.

"I mean I never thought it'd be that entertaining, I didn't think it'd last that long, and I didn't think it would've been such a dominant performance by Kell Brook.

"I thought it'd have been closer, especially early on, but as soon Kell Brook landed a shot, Amir Khan was badly hurt."

Asked where it all went wrong for Khan, he bluntly replied: "When his legs turned to Bambi in round one, which I actually said on Sky and I probably shouldn't have done, but his legs were gone.

"He showed greater powers of recovery for a couple of rounds, you've got to give him his credit, they could've pulled him out after three or four...

"It could've been stopped a bit earlier, people were just saying to me in the crowd there that the fight was stopped too early, but I disagree.

"I think the referee done Khan a bit of a favour there because he was getting badly hurt, he was getting badly beat up, his legs were gone.

"You've got to give him credit. I can't just stand here and say that it was a bad performance because it wasn't, he stayed in there, and he did himself proud in terms of trying to just be involved in the fight.

"But I thought Brook was class tonight. His timing was there, he was poised, landing accurate blows, and every time he clipped Khan on the chin, whether it was a jab or a right hand, Khan was bang in trouble."

Froch also insists that Khan should retire from boxing having taken so much damage over the years.

He concluded: "100 per cent, without a doubt, he's got to retire.

"And what a great retirement fight. He's been paid handsomely for another beating and he needs to say to himself that's it now, that'll do me. How much can you take?

"What is he, 35 or 36 years old? It's not healthy getting punched in the head. He's got to think of his future."
