Club career: Joined Manchester United as a 16-year-old apprentice, in April 1955, and remained with the club until 1970, when he made his 356th and final appearance in January of that year against Ipswich in the FA Cup. Made his first team debut two weeks after the Munich air disaster, playing as a left-winger in a patchwork United side, despite being the right back on the reserve team (he scored twice in a 3-0 FA Cup fifth round win over Sheffield Wednesday, in front of 60,000 people). Won two League medals (1965 and 1967) and was a member of the European Cup winning team in 1968. Joined Waterford as a player at the end of his United career and went on to manage the club.

International career: Won 19 caps between 1965 and 1970, making his debut against Spain in a World Cup qualifier (alongside United team mates Pat Dunne, Tony Dunne and Noel Cantwell) at Dalymount Park (May, 1965 - Ireland won 1-0).

Highlight: In the 1967-68 season Brennan had lost his place in the United line-up to Francis Burns but regained it two games before the end of the season and was in the team that won the European Cup against Benfica at Wembley.

Where is he now? Brennan, who recovered from triple heart bypass surgery some years back, lives in Tramore, Co Waterford, where he has his own parcel courier company. Was nominated for the FAI Hall of Fame, along with former United team mate Tony Dunne, last month.
