United weren't the first English club to move for the then Aberdeen manager.
Edwards recalled to the Daily Star Sunday: “I believe that he had talks with Arsenal and I think he had also given his word to Tottenham a few years before, that he was going there. But he changed his mind. He said his wife Cathy didn’t want to move that far south or something.
“We knew – and I don’t know how – that if we went in for him then he would be interested.
“And, of course, we made the phone call before we approached him.”
Edwards added: “For some reason, I had heard that he had it in his contract that if a club or United came in for him, they would release him.
