KSI steps back into the ring on Saturday night with an eagerly-anticipated fight against Tommy Fury that’s shaping up to be one of the most watched bouts of the year.

KSI, real name Olajide William Olatunji, has amassed a huge internet following since starting his first YouTube channel 15 years ago.

The fight with Fournier, who has a perfect record in boxing, will see the popular entrepreneur add even more money to his already impressive career earnings.
