Kell Brook is not worried about Amir Khan's decision to hire a new head trainer.

Khan has been inactive since July 2019, but he returns to the ring to face fellow former world champion Kell Brook in a grudge match at Manchester Arena on February 19.

During the last few weeks, Khan has been training in Colorado with Brian 'Bomac' McIntyre, who is best known as the head trainer for WBO welterweight champion Terence Crawford.

Crawford holds stoppage wins over both Khan and Brook.

Brook believes he's gained another advantage with Khan's decision to hire a new coach.

"Boxing is a young man’s game. Amir is the same age as me, you have got to listen to your body; recovery is as important as training hard in my eyes," Brook told the Sheffield Star.

"If he wants to go out with a new trainer he doesn’t know, an old-school American trainer, let him do that. I think it’s an advantage to me. I personally think he’s got it wrong by doing that.”

Brook camp member, Amer ‘Killa’ Khan [not related to the Bolton boxer], expects his fighter to secure a knockout win around the first half of the contest.

"I can’t even see Amir Khan going past six or seven rounds with Kell. I just think stylistically it’s all wrong for him with how he’s training," Amer said.

"With Amir, he’s been to the moon and back. He’s got a lot of miles on the clock. He’s had a lot of personal problems, bad knockouts, whereas with Kell you can see he’s had a full front-end change with two new eye sockets. Kell has always been very robust and strong. I think that’s what it’s going to boil down to – that brute strength, that power will come through. Kell’s not had those bad knockouts when you are stretchered out, they put a lot of miles on the clock.”
