"I've had my turn and done my stuff, no way will I be coming back".
Hopkins, who retired last December aged 51, warned against taking up that option, but still urged Klitschko to focus on making a quick comeback.
Speaking exclusively to Sky the day after the fight, Joshua showed some swelling around his left eye but said he was "good to go". "I had actually picked Klitschko to win as I thought this was just some jumped-up young guy from England".
We'd love to see the big Tyson Fury or Deontay Wilder showdown but fear the mandatory challenger situations may have to be dealt with, before we get what we want. I'll go for the old dog with the cane and the teeth that he can take out his mouth and put them in a jar at night.
"There's no quitting in him [Joshua]".
He insists he is not "desperate" to return to the sport but wants to meet Joshua, who beat Klitschko on Saturday to unify the IBF and WBA titles before immediately referencing a future bout with Fury. "He got hit with a really good shot but he got back up and even though he was still hurt he pulled through".More news: Warner sees big home-advantage in Uppal Stadium
"I can be the best Tyson Fury again, it didn't slip away, I just couldn't be bothered no more, it was s*** and I didn't value it, but now there's £30m involved". You're going to be financially challenged, scholastically challenged. You can take a guy with nothing, clean them up and next thing he's meeting the President of the United States or the Prime Minister of the UK.
Fury has sparred with Joshua in the past and added: "I always said Wladimir would be my easiest fight. It's a great leveller".
"You get two types of people in boxing, the outlaw and the Mr Nice".
With his transcendent appeal and ferocious physical attributes, the Olympic gold medallist leads a pack of hungry heavyweights with names like Fury, WBC title holder Deontay Wilder and WBO champ Joseph Parker all potential opponents. It is the heavyweights, it is me and AJ, no one else.
Joshua may want to get his hands on more belts and has the opportunity to do so. Once it is done, and if that is Anthony Joshua, the UAE could become a main hub for boxing.
Eventually it was Joshua, 14 years the 41-year-old Ukrainian's junior, who showed the heart and stamina to claim an epic contest in one of the greatest performances by a British fighter and one raucously celebrated by around 90,000 fans.
