Kell Brook criticised rival Amir Khan’s decision to use Brian ‘BoMac’ McIntyre ahead of their February fight.
Khan trained in Colorado with McIntyre along with WBO welterweight champion Terence Crawford, but Brook complained that both of them have dismissed the former world champion in the past.
“Khan’s trainer is new who he has never trained with before for any fight, how is he saying stuff to help him?" Brook told The Mirror.
"He doesn’t even know the man, he is the man who pointed his finger at Amir Khan and called him a quitter and was slagging him off. How are they in New York when his trainer was calling him a quitter and even Terence Crawford himself? Mad.
"Whereas I am settled like a duck to water, this is where I started and the only reason we weren’t together previously has been because of Covid. We do what we normally do and that’s work hard and be professional.
"That’s his opinion about the Ingles, Dominic knows when to push me and when to give me a day off. I am preparing for myself but obviously at the same time the way I am preparing myself is for the best Amir Khan.
"I have pushed 110 per cent, I will be physically and mentally ready to go with no excuses."
Khan fights Brook on February 19th in Manchester.
