Carl Froch says he is 'concerned' for one fighter as he makes bold Tyson Fury vs Oleksandr Usyk prediction

Carl Froch has offered Tyson Fury some advice ahead of his fight with Oleksandr Usyk.

The Gypsy King takes on Usyk on May 18 for the undisputed heavyweight world titles, and the Briton appears to be in the best shape of his career ahead of the bout.

And while Fury is clearly taking the fight more seriously than his previous encounter with Francis Ngannou, former super-middleweight champion Froch has urged the 35-year-old to put on weight to use against his rival.

Speaking to Fastest Online Casino he said: "I'm not sure if (Fury coming in light) is a good thing to be honest.

"That weight allowed him to bully Deontay Wilder, lean on him, tie him up and just have his own way.

"When it gets on top for Fury, when he's under pressure, he's able to sit back, get hold of the back of his opponent's neck, lean on him and use his body weight to get himself out of trouble.

"If he's losing weight and he's slimmer, he could struggle. I'd like to see him perform at a slimmer weight.

"His body and the way it looks is a product of his training camp.

"So maybe the nutritionist needs to step in and say, right, get some more red meat down here. Get some more protein down you and do some weight resistance exercises.

"I think he needs the muscle on now though. He needs to be bulking up muscle."

Fury, the WBC champion, has the chance to become the first undisputed champion in the four-belt era.

And ahead of his fight with Usyk, his promoter Frank Warren has suggested that he is in better shape than ever.

Speaking on talkSPORT Fight Night Warren said: "He's in tremendous shape not just physically but mentally.

"He's in a very good shape I think, and although he had that cut it has come good as he has had back-to-back camps.

"Physically I have never seen him look so well. The worry was going straight into a training camp was that he'd peak too soon.

"He has worked really hard so that he is in his best nick on May 18."
