Joseph Parker has zero chance of beating Anthony Joshua on Sunday.

That's according to boxing commentator Sir Bob Jones, as Parker and Joshua prepared to go glove-to-glove in front of 80-thousand fans in Cardiff on Sunday.

Sir Bob told Heather du Plessis-Allan he has little interest in the bout.

"I'd probably pay up to 100 grand not to attend. Joseph, I wish he didn't have to take this fight."
