Redknapp despairs at the way modern-day football supporters abuse the players they once cheered - and he hopes Zamora gets the reception he deserves.
"I don't know why you should get stick when you go back to a club where you have done so fantastically well," Redknapp said.
"Why do you abuse someone when they have given you good service and been a good player? I went to watch them play Juventus that night (in the Europa League). That was one of the best footballing nights I have ever been to.
"Fulham went 1-0 down and they were something like 4-1 down on aggregate (but came back to win 4-1 on the night) and Bobby ripped them to pieces.
"What a night of football, I loved every minute of it.
"Years ago people would go back to their old club and they would get a lovely ovation. Dear oh Lord, what has happened?"
