They remained in that company until their demise, their highest finishing position being 4th in the 1907–08 season.

Hegarty[7] (the latter from a quick free-kick while the London side was not ready), and Trechmann added a third after Clapton goalkeeper Wilding lost sight of a long shot.

Two late Clapton goals made the score look more respectable but the game finished with the northern club on the attack.
