The legendary former winger threw his diminutive frame at Bobby Smith’s cross to power a header past Gordon Banks in the 1961 FA Cup Final.
That made it 2-0 on the day and clinched the league championship and FA Cup double for Bill Nicholson’s great team.
Bobby had earlier fired us into the lead on 66 minutes and Terry’s header put the issue beyond doubt at Wembley.

It’s now over 54 years since that famous day but for Terry, now 80, the memories are as clear as ever.
“I missed a chance earlier, another header, I should have scored but I knocked it over the crossbar so I was delighted to get another chance,” he told us this week.
“Bobby did well, crossed from the right and I scored with my head. I remember thinking ‘I’ve just scored in the FA Cup Final!’ because back then, it was the ultimate to score in the FA Cup Final.
“That’s what every schoolboy and every footballer wanted to do and when we were kids, we all used to pretend to do that in the playground.
“It was the one game everyone watched, the biggest game of the season. I remember thinking all that when I was jogging back to the halfway line.
“That evening, myself and Bobby were talking and we both realised what we’d done. It was the schoolkids’ dream to score at Wembley. It was an unbelievable feeling.”

Thoughts of Leicester also had Terry talking about the man he beat that day - Gordon Banks, one of the goalkeeper greats and World Cup winner in 1966.
“It’s funny, I spoke to him after the FA Cup Final and he said ‘I think I should have saved your header!’” said Terry. “He was a lovely fella and a great goalkeeper.
“There were a lot of good English goalkeepers around at that time, but he was the best. Everyone remembers the save from Pele in the 1970 World Cup, that was incredible, but he had an all-round game, good in the air, great shot-stopper. As I said, at that time, he was the best English goalkeeper and there were a lot around when I was playing.”
