Billy Nelson
Trainer of Joshua’s chief sparring partner, Martin Bakole
"Anthony Joshua to win by stoppage between rounds eight and 10. He is too strong and powerful."
Alex Steedman
BoxNation expert commentator and pundit
"Anthony Joshua wins, in fact he should smash him. Alexander Povetkin is too small and the creaks are showing. He’s made for AJ who can finish this when he wants."

Former IBF world middleweight champion
"Anthony Joshua can take a late stoppage. I think AJ will go through some sticky patches early but will regroup and grind Alexander Povetkin down."
Adam Booth
Top trainer, including of David Haye and, currently, Josh Kelly and Ryan Burnett
"Anthony Joshua stoppage after seven rounds, having boxed cautiously at the start."
Kalle Sauerland
Chief Boxing Officer for World Boxing Super Series organisers, Comosa

Anthony Crolla
Former WBA lightweight champion
"Anthony Joshua inside six rounds but gets buzzed along the way once or twice."
