After spending the next two years at other clubs, firstly in Scotland with Hibernian (where he played on the losing side in the 1896 Scottish Cup Final) and then in England with Millwall Athletic of the Southern League, Robertson returned to Stoke for the start of the 1897–98 season.
At the end of Robertson's first season back at Stoke, in which he made 23 appearances, the club finished at the foot of the First Division table, having failed to win once away from home, and were required to enter the end of season play-offs, in a mini "tournament" also involving Blackburn Rovers and the top two teams in the Second Division, Burnley and Newcastle United.
[5] Stoke's financial problems prevented the club from strengthening the side for the 1898–99 season, other than the signing of goal-keeper George Clawley, who returned from Southampton.
[1] In February 1902, Robertson was a member of the Liverpool side who were surprisingly beaten 4–1 at Anfield by Southampton of the Southern League on their way to the Cup Final.

[11] Robertson met with a severe injury in the opening match of the 1903–04 season which put him out of the game until late November, during which period Samuel Meston took over from him.
