Quote: "It all depends on what happens that night. He has the right to fight him again if Daniel wins. So he can demand that. It all depends on how the bout ends.

I'm very pleased with his last three fights, which I think were essential to restore his self-belief and confidence, and he did it (won – ed.) in spectacular fashion," Warren said.
