This from another forum:

RJJ was asked in june 1995 if he feared anybody & he replied "Eubanks", when asked why he said "Not only does Eubanks have the most awkward style to get to grips with, but whenever hes challenged he responds viciously. he'd be challenged against me"

Also in december 1994 RJJ was quoted as saying "the only fighter who can give me a challenge is Chris Eubank"
