Kell Brook thinks Amir Khan is trying to steal the spotlight by talking about making a switch to MMA. The Sheffield-born fighter has hit out at his long-time British rival in the build up to his clash against Gennady Golovkin at London's O2 Arena on 10 September, suggesting Khan is jealous of the attention he is receiving.

Khan, 29, recently said he would be happy to face UFC champion Conor McGregor if he was given six months to train as an MMA fighter. But Brook has questioned whether Khan is serious with his claims and insisted he is solely focused on his bout against the undefeated Golovkin.

"I don't know if he wants a bit of attention talking about MMA," Brook told IBTimes UK at The Dorchester in London. "He's said that he hates me, that he wants to fight me... I don't know if he's on his period or what. You know, he's not on my mind.

"Like I said, I want that fight for the fans. But I don't need him. I've got Triple G and there are other massive fights out there. So if he wants to let the fans down, don't fight."

Meanwhile, Brook also rubbished comparisons between his upcoming fight with Golovkin, for which he is stepping up two weight divisions, and Khan's fight earlier this year against Saul 'Canelo' Alavarez, when he also fought a fully-fledged middleweight. Brook, 30, said he is naturally bigger than Khan and should not have any issues facing Golovkin, who is the current unified WBA (Super), WBC, IBF and IBO middleweight champion.

"I think Amir Khan was going up in weight and putting the weight on. Actually, I'm coming down to make 160lbs. Naturally, I'm a bigger guy. It's really hard for me to make 147lbs, as has been well documented," Brook explained. "He hasn't got the chin I've got, the toughness that I've got or the power that I've got. It's a completely different fight and you will see that on the night."
