Carl Froch says Anthony Joshua must 'sort his head out' before stepping into the ring with Oleksandr Usyk on August 20 and criticises the British boxer for parting ways with Rob McCracken.
Joshua is due to face Usyk for a second time this year after losing his WBA, WBO, IBF and IBO belts on an unanimous points decision at the Tottenham Hotspur stadium in September last year.
Froch - who is a former Super Middleweight champion - also says AJ must be 'more aggressive' and use his size and strength against Usyk to be in with a chance of winning their blockbuster bout.
