The Dons were drawn to face Icelandic outfit KR Reykjavik with the first leg scheduled to be played at Pittodrie on the 6th September. The Dons had prepared for the tie with a tough League Cup qualifying section that included both the Old Firm and Dundee United. Having started with a respectable 1-1 draw at Pittodrie against Rangers the Dons then suffered three straight defeats on the road, including a humiliating 5-0 drubbing at Tannadice. After earning a second point at Pittodrie with a draw against United, the Dons were out of the competition by the time Celtic visited the city the Saturday before the European debut.
23,000 fans witnessed the Dons make the perfect start when Jimmy Smith headed home in the 7th minute. The game quickly deteriorated into farce however when referee J.R.P. Gordon awarded Celtic a soft penalty when Lennox stumbled inside the box after losing out in a race with Dons keeper Bobby Clark. After two bookings for protests, Gemmell stepped up to take the spot kick and Clark made a fine save. To the consternation of the Dons fans Mr. Gordon was unhappy with the first effort and ordered a retake. Gemmell made no mistake the second time and beat Clark to draw Celtic level.
A rather irate fan ill-advisedly tried to attack Mr. Gordon, as did a dog. The fan received a life ban, but records don?t record the fate of his canine accomplice. Aberdeen then crumbled and Celtic ran out 5-1 winners in a game marred by crowd disturbances. So it was under this cloud of heavy defeats and media calls for ground closure that the Dons headed in to the uncharted territory of European football.
Knattspyrnufelag Reykjavik (lets call them KR from now on) were an amateur outfit, like all Icelandic teams of the time. The players had to pay £4 to join the club and they were also required to provide their own kit. Despite this KR had won their championship 19 times and their domestic cup six times out of the seven competitions. So apart from the match programme's references to local bonding with Icelandic trawlermen, very little was known about the opponents.
