The Reds spent £35m on Carroll after he burst onto the scene with his hometown club Newcastle United, who he re-signed with this summer.
"When I was here [at Newcastle], I'd go home, mess about with my mates, play football, go out, whatever, but I'd never watch football, I never knew any players," he told Newcastle's club website.
"I'd come in on the Friday or wake up on the Saturday morning saying, 'who are we playing?' It was just completely oblivious to all the football that was going on. I would work at the training ground and knew my tactics, but until we had a meeting I didn't know who we were playing, unless I asked someone.
"When I was in the helicopter down to Liverpool, I was like, 'I know Stevie G [Gerrard], I know [Jamie] Carragher. Who else?' My agent at the time had to tell me, and I would get it on Google and find out the team. So that's actually a true story.
"It's bad because it's Liverpool players, but it's not disrespectful - I just literally didn't watch football, so I didn't know."
