Redknapp has slammed West Ham for neglecting Bobby Moore before he died, saying they missed out on the greatest ambassador the game had to offer.
"England wasted him and West Ham could have had the greatest ambassador a club could have ever had," said Redknapp, speaking on a BBC Radio 5 Live show A Tribute to Bobby Moore.
"What disappointed me after Bobby died - yes, they named a stand after him and built statues - but when he was alive nobody ever really showed a lot of interest in him. I just found it absolutely amazing."
The 65-year-old then recalled the day Moore was EJECTED by a steward during a West Ham game - the last time the former Hammers captain ever attended Upton Park, according to Redknapp.
"I saw him get thrown out of the stands at West Ham," he said.
"I think they were playing in Division Two at the time, I went and sat in the N block, sitting next to Frank Lampard's mum as Frank Snr was playing. I think I'd come back from America. The stand was half-empty but I heard somebody shout 'Harry'. I looked round and there was Bobby. He said, 'I'll see you at half-time for a cup of tea'.
"He used to come in through a little side door at Upton Park, 10 minutes after kick-off, the gatemen and everybody idolised him. He'd sit at the back of the stands. But on this day, a steward came up to him - a nice guy, not his fault - and said, 'I'm sorry Bob but I've been told by the secretary that you're not allowed in without a ticket'. At half-time, I looked round and Bobby had left.
"I don't think he ever went back. Absolutely unbelievable. I'll never forget it as long as I live."
