Greig was a first team player for local club Lochee Athletic at the age of 14. After moving to London, he played professionally for
Old St Stephen's in the
Southern League from 1894 to 1898. In March 1936 he saved Dundee United from almost inevitable bankruptcy. Seven months later he sacked veteran manager
Jimmy Brownlie and took over himself as director-manager. This arrangement lasted a year and a half before Greig resigned in March 1938. ==Business career==
