In February 1934 the Aberdeen manager Paddy Travers accompanied Moore while on international duty against Belgium to help keep him away from alcohol. Travers was aware that Moore had developed a drink problem that would end his career prematurely. In May 1935 Moore was selected to play for the FAI XI in an away game against Switzerland but he was declared unfit to play after drinking too heavily while travelling to the game. Other similar incidents resulted in Moore being released by Aberdeen. Moore then returned to Shamrock Rovers and in 1936 helped them win a third FAI Cup by scoring in his third final.
