Jake Paul has accepted KSI's offer of a winner-takes-all fight at Wembley next year.
The YouTube rivals have a long-running rivalry which dates back to KSI's two fights with Paul's elder brother Logan. The pair have traded insults for three years without agreeing to fight but now appear close to an agreement.
KSI had tweeted earlier on Monday: "I'm going to send you a contract. We fight next year. Wembley Stadium. Winner of the fight takes all. 100 per cent of the purse will be on the line. Put your money where your mouth is and let’s finally end this. Will you accept Jake Paul?"
