Greig's efforts to restructure the team inherited from Wallace proved, for the most part, fruitless. The early years of the 1980s were ones of repeated frustration as the club continually failed to mount a challenge not only to Celtic, but to the resurgent New Firm of Aberdeen and Dundee United. The gloom of under-performance in the league was punctuated only by periodic cup triumphs. The Scottish Cup win of 1981, in particular, saw a triumphant performance by the enigmatic winger, Davie Cooper. The League Cup proved fertile territory for Rangers throughout the fallow years of the early 1980s, but it was the failure to add to the league triumph of 1978 that saw the growing pressure on Greig culminate in his resignation as manager in October 1983. During this period attendances at Ibrox dwindled from an average 25,628 in season 1978–79 to 17,681 in 1982–83.
