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.
