Sure he's got a chance, or at least he's right to think he's got a chance.
I'm a massive fan of Callum Smith and I think it's only a matter of time before he's a 2 weight World champ.
But Fielding's been around a bit, he's unbeaten and it's a good British title fight.
I don't know if Fielding is any better than Rebrasse, because I think that was a very good win for Smith, and I think Callum is definitely heading in the right direction.
If Fielding didn't have a chance, it wouldn't be such a good fight, but I do see Smith coming out on top. I certainly hope so anyway.
