Allen's goals could have helped land a treble but he had to settle for an individual double in the shape of the PFA and Football Writers Player Of The Year Awards.
"I say to this day, given in that first season we were so close on all three fronts, we would have all hoped to have won something the following season," recalled Allen. "But unfortunately, that group of players disbanded."
Allen, who joined us from QPR in 1981, profited when Pleat - then manager, now our director of football - introduced a five-man midfield supporting him as a lone striker.
"I remember it well," said Allen. "David Pleat told the players on the Friday before a match at Oxford that we would be playing this system and he would take full responsibility for the results.
"It worked perfectly for us. We had clever players and players of great ability who were able to take on board exactly what he wanted. It worked for that team."
Allen moved to Bordeaux in March 1988 and went on to play for Manchester City, Chelsea and West Ham. He is now a pundit for Sky Sports.
