Born and brought up in the suburb of Cabra in Dublin on the 30th of April 1954, Gerry Daly kick-started his round ball career at the widely acclaimed soccer academy of Stella Maris Football Club in the suburb of Drumcondra before the promising and precociously talented youngster tried out his luck with famous League of Ireland club Bohemians of Dublin. An accurate shooting and sweet passing midfield dynamo with attacking instincts and natural fitness too, the Dalymount Park favourite was eventually brought to British football and Manchester United by newly appointed Old Trafford boss Tommy Docherty for a bargain transfer fee of around £20,000 at the end of the 1972–73 season. After being handed his English First Division debut for Manchester United in an embarrassing and humiliating 3–0 defeat against Bertie Mee´s Arsenal side in front of a 50,000 plus home crowd at Highbury Stadium on the opening day of the 1973–74 campaign, Gerry Daly went on to accumulate 111 English Football League appearances for The Red Devils of Manchester, contributing a most creditable twenty-three goals during the process.
Despite Manchester United being relegated to the English Football League Division Two in 1973–74, he played consistently well in his first year and he was an important part of the exciting and youthful Old Trafford team which clinched the English Second Division Championship title three points ahead of Ron Saunder´s Aston Villa during the 1974–75 season and went on to take the English First Division by storm the following fodbold online campaign. The midfield engine from The Big Smoke was also an integral constituent of the confident Manchester United Squad who reached the FA Cup Final at the Wembley Stadium in 1975–76 only to experience a devastating and embarassing 1–0 defeat at the hands of Lawrie McMenemy´s Southampton. Along their way to the FA Cup Final in 1976, The Reds of Manchester had managed to overcome Oxford United, Peterborough United, Leicester City, Wolverhampton Wanderers and finally defending English First Division Champions Derby County at the Hillsborough Stadium in Sheffield, while Lawrie McMenemy´s plucky Southampton players had managed to knock out Aston Villa, Blackpool, West Bromwich Albion, Bradford City and then Crystal Palace at Stamford Bridge in London. But following a long and bitter dispute with the sometimes controversial and very often flamboyant Manchester United Head Coach Tommy Docherty in the spring of 1977, Gerry Daly was deemed surplus to requirements by the firebrand Old Trafford manager and, as a logical and natural consequence of all this, the offensive oriented midfield administrator was placed on the transfer list with the wayward playmaker subsequently leaving the club for fellow First Division side Derby County for a transfer fee of around £175,000 at the back end of the 1976–77 season. And even though Daly was quickly to be reunited with his previous manager when The Doc was handed the head coaching reigns at Derby at the front end of the 1977–78 campaign, the dependable and determined perpetuum mobile nonetheless proceeded to produce an acceptable total of thirty-one goals in 112 English Football League appearances for The Rams before he left the newly relegated Baseball Ground club at the end of the 1979–80 season.
The Dubliner then had a summer loan spell with Foxborough side New England Tea Men of the North American Soccer League which at that time included great teams like the Fort Lauderdale Strikers, Los Angeles Aztecs, New York Cosmos, Tampa Bay Rowdies and Washington Diplomats and also featured household footballing names along the lines of Carlos Alberto, Franz Beckenbauer, Giorgio Chinaglia, Johan Cruyff, Roger Davies, Alan Hudson, Johan Neeskens, Bruce Rioch, Julio Cesar Romero, and Wim Rijsbergen. After starring in over forty first team games for the Foxborough Stadium club, the still ambitious and technically gifted central midfielder decided to join forces with League Division One team Coventry City for a activity life transfer fee estimated to be somewhere in the region of around £300,000 at the beginning of the 1980–81 season. At Highfield Road Stadium, the vastly experienced veteran player teamed up with other seasoned campaigners such as Jimmy Blyth, Mick Coop, Roger Van Gool, Big Jim Holton, Steve Hunt and Tommy Hutchison and he would enjoy a new lease of life during the early part of the 1980´s. The Irishman received his Football League Division One debut for Gordon Milne´s Coventry City in a goallless draw against defending First Division Champions Liverpool at Highfield Road on the 19th of August 1980, and he racked up nineteen Football League goals in eighty-four outings for The Sky Blues until he waved goodbye to the Warwickshire club at the end of the 1983–84 campaign.
