6th September 1921 Celtic 4 Dumbarton 0
In season 1921/22, Celtic needed a good start to compete with a resurgent Rangers side who had won the title the previous year.
Thanks to goals by forwards Joe Cassidy, just back from war-time service and Archie Longmuir, who had come in the previous year from Ardrossan Winton Rovers, Celtic had won three and drawn one of the first 4 league matches.
On this day in 1921, Dumbarton came to Celtic Park and found Tommy McInally in sparkling form, showing all his tricks as he scored two. Not to be outdone, Joe Cassidy also hit the back of the Sons net and Patsy Gallagher, as usual controlling the play, was another who made the score sheet as Celtic won 4-0.
The shut-out was good news for Irish goalkeeper Frank Collins, making his debut between the posts.
