His most memorable game for Southampton came as they gained revenge against Nottingham Forest on 10 November 1979. Forest, then reigning European champions, were unable to cope with Boyer and Mick Channon up front and suffered their worst defeat since Brian Clough took charge four years earlier. They had a chance of winning a point when Garry Birtles brought them back into the match at 2–1 in the 56th minute, but Boyer struck twice in seven minutes to complete a memorable 4–1 victory. Boyer's second goal completed a five-man, six-touch move and the shot left goalkeeper Peter Shilton stranded from a Channon cross.
