An extremely useful centre-forward was supplied in Foster, who played really well to his insides. He kept them well together and gave them plenty of splendid opportunities, of which, for the most part, poor use was made."[3]
He scored the decisive goal in the 1914 University Match,[5] and was appointed secretary of the university club for the 1914–15 season.[6]
In March 1914, he was selected for a combined Oxford and Cambridge Universities team which beat Chelsea in "the first game in London between an A.F.A. side and a professional team for many years", though he was not at his best: "his shooting was poor, and he passed too much to the left wing".[7] That same month he assisted Old Reptonians to victory in the final of the Arthur Dunn Cup; he contributed many of the 33 goals they scored in reaching that stage, though his playing style had developed an element of selfishness:
A. W. Foster has scored most of the goals, and as a centre-forward he only just lacks greatness, but on Saturday he frequently forgot to make openings for his inside-forwards.[8]
Foster played for the major amateur clubs of the time, both Casuals, for whom he took part in the final of the 1913 A.F.A. Cup,[9] and Corinthians, touring Brazil[10] and scoring twice in a losing cause on the club's return to first-class football against the English Wanderers, an amateur eleven selected by the Football Association.[11]

The Oxford goalkeeper probably made an error of judgment in running out, and Foster was able to turn the ball easily and gently into the goal.
