When was the fateful moment? In his own words, right when he tipped a bucket of water over Harry Redknapp's head.
Obviously its never a good practical joke to make on your boss, even if they were celebrating beating Manchester City and qualifying for a top four spot.
Redknapp seemed to take it in good spirits, but Bentley believes the manager never forgave him.
Speaking to the Mirror, he said: "It was all good natured. But he definitely didn't see it like that. It was a celebration and nothing more,
"That season, I'd played 20 games up until that point and we got into the Champions League. I'd started 15 games in a row and, even though I didn't start that game, we were just celebrating a brilliant achievement.
"He never said anything to my face about it - he didn't really ever say much to me at all - but I knew I was always up against it after that. I hardly got another look-in.
"I've played 42 games in four years. I should have played 42 games in one season, let alone four. It's been like banging my head against a brick wall at times."
Watch the incident here...
Do you think Bentley is right about this, or is there more to it than that?
