I have watched Parker since he was WBO champion, beating Ruiz and Hughie in his title defences. I did not rate him as a top tier heavyweight and he handed the title to AJ when they faced one another in the unification bout.

Since Parker joined Andy Lee he has got considerably better, more aggressive and exciting to watch.

I predicted Parker would lose to Joyce and beat Wilder (as did Primo). So know Joseph is now a top tier heavyweight and should face Fury v Usyk winner for the title.

This fight is really tough for Parker.

Zhang is a huge unit, southpaw and coming from 2 sensational wins against Joyce. Unless Zhang gets old, tires quickly in the contest and Parker's speed is too much for him I can only see Zhang winning.

Saying all that I would be rooting for Joseph Parker.
