Wardley pulled off a sensational stoppage of Parker in the 11th round at The O2 on Saturday night in a bout to decide the next challenger for Usyk’s WBO belt.
The Ukrainian had delayed a world title defence against mandatory challenger Parker due to an injury, but Warren is confident that the WBO, WBA, WBC and IBF belts will all be at stake in a fight against Wardley.

Warren was full of praise for the boxer from Ipswich and assured the crowd that Wardley’s fight against Usyk should happen.
“He said he wants to [fight Usyk] so that’s what it’ll be,” Warren told DAZN.
“He’ll be fighting for all four belts, because that what he deserves after a fight like that.”
Wardley appeared behind on the scorecards when he launched a ferocious attack on Parker in the 10th, then pinned the Kiwi on the ropes in the following round before a sustained assault prompted referee Howard Foster to wave it off.
The remarkable rise of Wardley continues as the former white collar fighter is now set to fight the No 1 heavyweight in the world.
Warren added: “Fabio’s is a story I’ve never seen before. Honestly, I’m amazed that someone who has zero amateur experience – with 20 fights – comes out and beats a world champion.
“What a fight. That was edge-of-your-seat stuff – credit to both of them.”
Wardley himself was elated after his sensational upset against Parker, whose professional record now slips to 36-4.
“What I lack in experience, I make up for in chin, heart, fight,” he said.
“It sounds like a dream but this is real life. I’m proof of hard work, of passion, of never giving up.
“It’s a massive thanks to Dillian Whyte. That man looked after me – he changed my life. He deserves everything from me.
“I’m not taking anything away from Joe but I wasn’t hurting that much! I put my feet in silly positions but I wasn’t busted. I’ve said before I’m not the cleanest fighter – but I get the job done.”
