And he revealed an insight into how his preparation has gone with a short clip throwing left hooks.

KSI posted: “I feel there’s something big that I’m missing but ah well it’s probably nothing important…

“Anyway get your tickets to see me KO boring Alex this August 27th.”

KSI has three times fought before, starting with a win over Joe Weller, 26, in 2018, the same year he drew against Logan Paul, 27.

The Londoner then won the rematch with Logan by split-decision in 2019 but he has not returned since, instead focussing on music.

That will change next month against Wassabi, who in March beat KSI’s brother Deji.

KSI took time away from boxing to focus on his fledging recording career but he has since dedicated himself solely to training.

He said on Harvey Ubhi’s YouTube channel: “I think for me, the focus is purely on training.

Let me just focus on training for like a month, even in this month I’ve had people message me being like, ‘Can you film or do this press thing, show up for this?’

“Like, guys, no. Let me just f***ing train bro.”

KSI added: “I just need to make sure the skills are on point, just a machine.

“I want people to be like ‘Jesus Christ’, like cool, on to the next. I just want to see see what I can do.

“I’m doing this for me than for anyone else. Just to see how far I can go.”
