Anthony Joshua is still basking in glory following his defeat of Gary Cornish at the London O2 Arena on Saturday night.
The Olympic Champion took just 90 seconds to secure his victory and stun Cornish, who had started on the front foot.
And Joshua, who will now face a grudge fight against fellow Brit Dillian Whyte at the same venue on December 12, concedes he did not expect to secure victory so quickly against the Scotsman.
"No, not at all. Big Gary come game, trained hard, he's been undefeated, I thought it would be a tough fight for sure," Joshua said on Sky Sports News HQ.
"While it lasted he came forward and put me under pressure, but I dealt with it and managed to catch him with some haymakers."
After such a swift victory, the 25-year-old had trouble unwinding and broke his normal routine to watch Floyd Mayweather defeat Andre Berto to retain his WBC and WBA welterweight titles.
"It's hard because there is so much adrenaline and normally I go back and do the pads to try and get rid of that adrenaline, but yesterday I didn't, so what I did was stay up and watch the Floyd Mayweather fight," Joshua said.
Joshua paid tribute to Mayweather, who has called time on his career after 49 straight victories.
"Well, he set the standard so high I think athletes in my generation that are younger than myself are going to look up to Mayweather," Joshua said..
"He set the bar so high people are to aspire to be just like him."
Joshua plans to have a very short rest period before returning to training ahead of his fight with Whyte, who took his undefeated record to 16 on Saturday's undercard.
"The main thing is staying in the gym, keeping it simple, don't get carried away," Joshua said.
"It's going to get tougher for sure. Very, very tough. So what I've got to do is stay there, stay working hard, and I hope to keep on progressing as I move on and put on the same devastating performances as last night.
"I've got 12 weeks now until December, and normally I take a 10-week camp, so I might just relax for five days or so.
"Eight weeks, 10 weeks will just fly by, so I have to stay focused."
