Dundee United beat Celtic 2-0 back in the 1988/89 season thanks to a dodgy penalty, an own goal and a nightmare of a game for Celtic defender Lex Baillie.

Season 1988/89 was tough in the Scottish Premier League; Celtic were aiming for a second consecutive title while 80s Aberdeen and a newly revived Rangers side both seemed capable of winning the championship.

United had also had a good decade so far, getting to the UEFA Cup final in ‘87, the semis of the European Cup in ‘84 and winning the league in ‘83.  So when Celtic arrived at Tannadice to face Dundee United they knew they were in for a tough match.

The goal which broke the deadlock came from a dubious penalty won by a young Kevin Gallagher who latched onto a Billy McKinley ball before diving to the ground in the box under Baillie's challenge.

Once Gallagher had managed to stop laughing on the ground and the furious Baillie and Paddy Bonnar had had their say to the referee, a fresh-faced Mixu Paatelainen stepped up to bury the spot kick.

Not only was he wrongly penalised for the first goal, things went from bad to worse for Baillie when he scored the own goal later in the match which sealed the victory for United.

The Arabs finished the season in fourth place just two points behind Celtic who had lost out to new champions Rangers and runners up Aberdeen.

Plagued by injuries, Lex Baillie left the game soon later to become a policeman while Paatelainen was twice top goalscorer for Dundee United and is the third all-time top goal scorer for Finland.
