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.

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.”
