Jarrell Miller says “posh” world champion Anthony Joshua has an “image problem” as the pair prepare to meet at Madison Square Garden on  June 1.

Joshua, 29, will defend his IBF, WBA and WBO titles against unbeaten American Miller.

Miller believes Joshua’s claims of “being a thug” are not true because of his home counties upbringing.

Brooklyn-born Miller, 30, grew up in a “rough broken home” and says he took up combat sports to defend himself after being attacked in the street.

Joshua, meanwhile, was raised in Hertfordshire but, until the age of 14, lived on Watford’s Meriden estate – one of the town’s most deprived areas.
