Anthony Joshua admits he is looking past upcoming opponent Alexander Povetkin with eyes on a huge mega-fight against Deontay Wilder, stating he’d be “very annoyed” if a deal couldn’t be agreed.

Joshua wants Wilder to accept a $15 million offer to face him to decide the undisputed world heavyweight champion in front of a 100,000 crowd at Wembley Stadium on April 13.

The fight could generate up to $100 million and would be the first time all four major world heavyweight titles were on the line.

Joshua (21-0, 20 KOs), 28, hopes victory over Povetkin on Sept. 22 leads to an even bigger clash with Wilder (40-0, 39 KOs), 32, despite talks stalling with the WBC champion.

MEANWHILE, Tyson Fury says negotiations over a fight with Deontay Wilder in December are “very close to being done”.

The former heavyweight champion returned to the ring in June with a stoppage victory over Sefer Seferi at the Manchester Arena and takes on Francesco Pianeta in Belfast on August 18.

Fury has vowed to reclaim the world title and a fight with Wilder – the WBC heavyweight champion – would be only the 29-year-old’s third fight in nearly three years.
