Anthony Joshua has admitted he gave coach Angel Fernandez the responsibility of picking his new trainer ahead of Saturday's rematch with Oleksandr Usyk.
Joshua is due to face Usyk for a second time this weekend after losing his WBA, WBO, IBF and IBO belts in an unanimous points decision at the Tottenham Hotspur stadium in September last year.
Joshua heads into the rematch with a new coaching team after parting ways with Rob McCracken - who helped guide him to an Olympic gold medal and become the unified heavyweight title holder of the world twice.
