After the appointment of the new manager, Jack Charlton, Gregson made one further appearance in the first team as a second-half substitute away at Exeter City (score 1–1), and although he never featured in the new manager's future plans, he continued to perform to a high standard, as demonstrated by various match reports, in the reserve team. During one match, Saturday, 4 March 1978, giving Wednesday a 2–1 victory, he scored both goals passed the Manchester United goalkeeper, Alex Stepney, who had played for United during the 1968 European Cup Final. It was reported, "Wednesday's first goal was rocketed into the net by Gregson" and "Gregson crowned a workmanlike performance with the winner (a header created from a cross by the ex-WBA &amp; Scottish International, Bobby Hope) five minutes from the end".
