KSI declared "I am the greatest YouTube boxer" ahead of his return to the ring on August 27.
The Brit has been out of action since beating Logan Paul in Los Angeles in November 2019.
YouTube boxers like Logan's brother Jake have flourished in KSI's absence, although the 28-year-old is set to return to the squared circle.
Since November 2019, KSI has focused on his music career – but he announced last month that he'll be making his boxing comeback on August 27.
His opponent is yet to be announced, although he could face old foe Jake Paul.
Whoever he fights, KSI is confident that he will make a winning return.
