"I hit him way more times than he hit me," Gallen said. "I won that fight.
"I hit him way more times than he hit me, there's no doubt about that. One judge had it right, the other two had it wrong.
"I'll fight him wherever, just get some judges that can score."
Hall didn't seem too interested in the rematch straight after the fight, saying he was keen to put the attention back on his partner and own life.
But Gallen continued his belief that he should have had his hand raised after the final bell when he spoke to the Main Event crew from his locker room.
"I thought I out jabbed him in the final rounds and was constantly going forward, that's what you're supposed to do in boxing and where I thought I won the fight," Gallen said.
Hall rued his lack of an opportunity after being told by his corner Gallen was gassed after the fourth round and needed to get after him.
"I needed to push the fight a bit more and I didn't do that," Hall said.
"Still thought I landed the cleaner shots throughout. I wasn't happy with my performance, I probably paid him a little too much respect tonight.
"I'm a combo puncher and I didn't do enough to get that off tonight."
