Even cultured Dutchman Rafa van der Vaart had to be given a lesson about 1961 Double winner John White by his gaffer.
Redknapp said: "Rafa is a real football person and I was telling him how John got killed on the golf course — struck by lightning.
"It was a long time ago but the history of the football clubs, they don't know about it unless they were brought up with it as kids.
"I come from the East End. We knew about the Arsenals, the Chelseas, we knew the players. They don't now.
"Rafa could probably tell me about players at Ajax or somewhere, but in this country they don't know do they? I think it's a disadvantage. If I asked Frank Lampard he would tell you all about players. He has been brought up with it."
