History of Celtic F.C. (1887–1994) As the season progressed, Frank McAvennie arrived from West Ham and young forward Joe Miller – a very promising prospect – was signed from Aberdeen. This new-look Celtic side, captained by Roy Aitken, quickly gelled and embarked on a 31-game unbeaten run, culminating in a historic League Championship and Scottish Cup double win in the club's centenary season.

Celtic clinched the league title on 23 April 1988 with a 3–0 win

The less attractive matches, against the Irish League XI or the League of Ireland XI, were spread around Scotland more evenly. Grounds in Dundee (Carolina Port and Dens Park), Edinburgh (Easter Road and Tynecastle), Paisley (Love Street) and Motherwell (Fir Park) were used in addition to Glasgow. Smaller stadiums were also used in Glasgow itself,
