Charlton wrote in the United Review:
"I always liked playing against West Ham as they had a reputation for good football and for creating talented young players within their own ranks. When I went to Upton Park for our FA Cup third round tie I was thoroughly impressed to see those traditions intact.
"I was reminded of the club's great history. Bobby Moore, Martin Peters and Geoff Hurst are well known for playing for England in the World Cup final, and it's always nostalgic to see the lovely statue of the trio erected by the club in their honour. It's similar to the one at Old Trafford with Denis Law, George Best and myself.
"At the time when we used to come up against those three, they were always difficult to beat. They were genuinely world class and whenever I played with them for England I always felt proud to be lining up alongside them.
"They were extremely well coached by Ron Greenwood and they were known for their coaching ability at Upton Park. I always watch to see how they're doing, even now. West Ham - like United - have an attacking philosophy."
