The Queens Park Rangers boss was at Highbury to see the memorable fixture and remembers being devastated when news of the air crash in Munich filtered through days later, following the midweek European Cup tie against Red Star Belgrade.
In an exclusive interview with ManUtd.com, the popular manager spoke with real affection for the players he admired as a schoolboy and the team that many tipped to become the finest in the world.
"I think I was 10 at the time and my Dad and I were big Arsenal fans," recalled Redknapp. "We used to stand on the same spot every week and Manchester United coming to Arsenal was the big game.
"United were such a fantastic team with the Busby Babes and it was an amazing game. United came out and just murdered Arsenal, going 3-0 up, but Arsenal came back and it ended up 5-4 and a fantastic game.
"It was a great team. It was amazing to be so young and play for England like Duncan Edwards did and he could have been one of the best players in the world. Eddie Colman, they used to call him 'swivel-hips', what a footballer he was, and Roger Byrne. Harry Gregg is a great character, I still talk to him sometimes, and he was as brave as a lion in goal.
