In 1961, a shy teenager from Belfast had to be coaxed back to Manchester after suffering from home sickness during his trial with United. At the second attempt, however, George Best went on to enjoy one of the outstanding United careers and established himself among the Reds' record scorers and appearance-makers.
Though he perished in the Munich disaster, Dublin-born striker Liam Whelan had a goalscoring ratio comparable with anybody else, averaging over a goal every two games in under four seasons with the Reds' first-team. Less prolific was another Dublin export, Frank Stapleton, but the line-leading powerhouse nevertheless impacted on Old Trafford as an outstanding member of Ron Atkinson's Reds.
So too did Norman Whiteside, who burst to prominence as a goalscoring debutant at just 17, then etched himself on history as a goalscorer in three Wembley cup finals for the Reds before his career was cruelly curtailed by injury.
