However, once he was featuring in the League he clearly attracted attention from elsewhere, at the end of his first season at old Douglas Park Liverpool came in for him, the club with which he would officially remain for the best part of a decade, including in 1914 at centre-forward a lost FA Cup Final and the War years. But it would be a period not without a problem, when in 1915 he was implicated in match-fixing and was banned by the FA. It prompted him to return to Larkhall to play outwith the Scottish League and then sign up with the Glasgow Highlanders for the duration.

Yet with the end of hostilities his ban was lifted and he, already aged thirty, was able n 1920 to return to Anfield and that same year be capped for the first time, against England, at inside-right, scoring twice. And that first international start would lead the following year to two more although by then he was turning out for Manchester United at the start of several more seasons of moving from club to club, mostly back in Scotland. 

In part it must have been because in 1918 on leave from France he had married Larkhall-girl, Mabel Howe, with whom he had four children, with three seeming to survive. Moreover, the last of them was in 1925 born in Edinburgh an explanation perhaps being that after just a year at Old Trafford he had in 1921 returned to Hearts and, even though he quickly fell out with the club, once installed remained in the capital whilst for four months plying his trade, curiously, with Torquay then re-joining Hamilton for the next three seasons, topped of final few months at Raith to 1927.

By then Miller was almost thirty-seven, and whilst the boots were hung up he would remain in the game short-term coaching at Dunfermline and then Barrow, there for a few months also managing to 1930. But that seems for him finally to have been enough. The family would return to Larkhall, where he would, post-War at least, become a Security Officer. At the time of Mabel's death, aged sixty, in 1963 he would be recorded as Works Policemen and then as a Retired Security Officer on his own passing in Girvan at sixty-eight in 1958.
