Undefeated boxing superstar Terence Crawford has a wish ... and that wish is also undefeated, and also a boxing superstar -- Errol Spence, who Crawford says he wants, no, HAS to fight.
Spence just dispatched Mikey Garcia in a 12-round beatdown that made many believe Errol is the very best fighter in the world at 147 pounds.
Crawford -- who's gearing up to fight Amir Khan on April 20, says that ain't so ... and told us there's only one way to prove he's actually the guy and that's going to make the fight with Spence.
