I am almost certain that Floyd Mayweather will beat Conor McGregor when they fight, but in sport there is always a chance that the unthinkable could happen.

Usain Bolt just proved that Father Time can catch up with anyone at the wrong time as he failed to win both the 100m and relay race at the World Championships, so if it can happen to the greatest athlete of our generation then could it happen to the greatest boxer?

If Father Time can catch up with the greatest athlete of our generation then could it catch up with the greatest boxer?

For years we've watched Bolt to see just how fast and good he is, to see if he can break records and never thought he would be beaten. It's been the same with Mayweather.

But time did catch up on Bolt and although I very much doubt it will, there's a chance that it could happen to Mayweather. Don't forget he has not boxed in two-and-a-half years.

The only chance I am giving McGregor in this fight all depends on Mayweather. If he has aged dramatically since he retired, if he's lost his defence, lost his legs and has no feet - not literally - then there is a chance. But it's only a small chance.

You used to watch Bolt and wonder what would happen if he got a bad start or does something wrong and we ask the same questions when talking about 'Money'.

There is no doubt that McGregor will be awkward and all this strange stuff he is doing in the build-up is good. He has to be unorthodox and make Mayweather feel uncomfortable.

We know 'The Notorious' has a huge personality, but so does Mayweather and that is what has made this a massive event, you look back on his fights and no matter what, people always get up to watch it.

Bolt is the same in athletics, it doesn't matter if you can run fast, you need that massive personality like he has, that is what draws everyone into watching the event.

Until recently, we have always known or thought that Bolt is going to win, but we still set the alarm clock and make sure we're sat in front of the TV, no matter what the time is, or where it's coming from. We will do the same this weekend.
