Speaking ahead of coaching our Legends team for the first time, at Southampton on Saturday (15:00 GMT kick-off), Pancho takes up the story.
"A lot of people forgot Tommy Doc went to Hull as Terry Neill's assistant, so did Tommy Cavanagh," he said. "They obviously got to know me quite well.
"Tommy, when he left, said: 'I will come back one day and sign you, Pancho'. I was like 'I believe you', nobody believed Tommy! But he came back and bought me, once they got relegated, which I didn't mind at all. It's just the name, Manchester United, and the history of the club and they had tremendous players as well.
"You had Martin Buchan in the team, Alex Stepney was still going great. Then, after that, we managed to get Gordon Hill, Stevie Coppell, Jimmy Greenhoff. Lou Macari went back into midfield from being a striker because, when I first signed, Lou played up front with me. When he dropped to midfield, him and Sammy McIlroy were fantastic. You had Buchan at the back, with Brian Greenhoff as well, so we had a super team.
"All we wanted to do was go and attack teams and everybody loved it. Now, when I do the hospitality, they still love talking about that era."
