I can’t give you a second-by-second guarantee. No one can. But the safe bet is: head to your sofa by 9:30 PM UK time. Have your phone charged. Have your snacks optimised. If you’re watching on DAZN, make sure your subscription isn’t expired—that’s a buzzkill no one needs.
And remember: if the fight does start at 10:15 PM? You win. If it starts at 11:45 PM? You get to complain loudly on Twitter. Both are victories in their own way. Now go clear your schedule. The circus is coming to town.
