Renton FC was formed in 1872. West Dumbartonshire was a nursery of Scottish football, with Renton's neighbours Vale of Leven and Dumbarton also producing strong teams in this era. In 1888 Renton beat Cambuslang 6-1 in the Scottish Cup final. It was their second cup win.
In the 1888 FA Cup final in England underdogs West Bromwich Albion beat Preston North End on 24th March . West Brom. then issued a challenge to Renton. They would come to Scotland and meet Renton on a neutral ground to determine the‘Champions of the United Kingdom’ – and the World.
Renton accepted the offer, and on May 19th the two cup winners met at Cathkin Park, Glasgow.
The match was played in appalling conditions, Renton running out 4-1 winners. Renton's team included 19 year old Neil McCallum, who later that year would score the first ever goal for Celtic.
