Charlton, who later handed Houghton his international debut in his first match in charge of Ireland against Wales in March 1986, died on Friday aged 85, his family announced in a statement.
As tributes poured in from his former clubs and the Premier League announced black armbands will be worn by players at all matches this weekend, Houghton labelled Charlton a “legend” after winning a clutch of honours with Leeds as a player and helping the Republic qualify for the 1990 and 1994 World Cups and Euro 1988.
“He left an indelible impression on our national game and was guaranteed an affectionate and warm welcome wherever he went. A huge presence on and off the pitch, Jack will never be forgotten at Wembley.”
Manchester United manager Ole Gunnar Solskjaer paid tribute to Charlton at the start of his press conference on Saturday morning.
“It’s very sad news and a legend of football and a gentleman,” he said.
“I watched Norway play Ireland in the World Cup ’94, but he was always so passionate when he was speaking and it’s sad to hear.”
UK Prime Minister Boris Johnson tweeted: “Jack Charlton was a football great whose achievements brought happiness to so many. My sympathies are with his family and friends.”
