The new WBA interim super-bantamweight champion knocked Munroe down twice to seal the win in the sixth round on the undercard of Ricky Hatton's ill-fated comeback.
"That was my best performance yet and I think it showed that [my goal of being world champion in 2013] is a realistic expectation," he said.
"Munroe is tough, no one has ever stopped him before, but I was hurting him and it shows I have the power to go up a level.
"I've always dreamed of being a world champion. I want to beat all the top guys in the division, that's who I want to be able to mix with, and this performance proves I'm on the right track."
His manager Paul Speak told The Bolton News: "I'm sure from that performance that the Americans will be watching and wondering.
"It's down to [promoters] Team Hatton to come up with an opponent and tell us where they see him going, but I don't think it's going to be too far away before he is going across to fight in America."
