Standing just 5ft 6in tall and weighing 11st 4lb, McNiven was known for his agility and ability to find holes in the tightest of defences, while his ability to make an impact when he came off the bench saw him nicknamed 'Supersub'.

David Scott McNiven was born on 9 September 1955, in Stonehouse, Scotland. From a young age, McNiven showed a keen interest in football, a passion that would shape his future. His early years were spent honing his skills on local pitches, where his talent as a forward quickly became evident.

His skills caught the attention of scouts, and in 1971, McNiven joined Leeds United, marking the beginning of his professional career.

The 1975/76 season saw McNiven begin to make his mark at senior level. McNiven was a prolific goalscorer in the Juniors and Reserves, scoring three hat-tricks in the Central League. Jimmy Armfield gave McNiven his first-team debut on 8 October 1975, in a League Cup-tie against Notts County at Elland Road. He went on to make a couple of substitute appearances towards the end of the season, scoring in his first league game, a 2-1 victory against Manchester City on 17 April.

His real breakthrough came the following campaign when McNiven made 18 league appearances, scoring 5 goals. His increased involvement was a testament to his hard work and determination. McNiven’s ability to come off the bench and make an impact continued to be a valuable asset for Leeds United.

His finest moment caame on 23 October 1976 when he scored an 89th minute equaliser against Liverpool at Elland Road to rescure a point against the reigning champions.

While McNiven's first-team opportunities were limited, this was understandable given the competition at one of the country's finest clubs. The team boasted several wonderful forwards, including Allan Clarke, Peter Lorimer and Joe Jordon, and breaking into the first team required exceptional performances or great fortune.

McNiven’s perseverance and dedication were evident as he continued to work hard in training and make the most of his opportunities. His time at Leeds United was a learning experience, helping him develop the resilience and skills needed for a successful football career.

In February 1978, McNiven transferred to Third Division Bradford City in a £25,000 deal, widely considered as a snip. This move marked a significant period in his career, as he became a key player for the team, though he couldn't help the Bantams avoid relegation at the end of teh season. Over the next five years, McNiven made 212 league appearances and scored 64 goals for Bradford City. His performance on the field was instrumental in many of the team’s successes during this period. McNiven’s ability to find the back of the net made him a fan favourite and a crucial part of the squad.

After leaving Bradford City in 1983, McNiven joined Blackpool. His debut for Blackpool was memorable, as he scored the only goal in a victory over Rochdale. McNiven continued to be a reliable forward for Blackpool, making 49 appearances and scoring 11 goals during his time with the club. His contributions helped Blackpool navigate through challenging seasons, and his experience was invaluable to the team.

In 1985, McNiven had a brief stint with the Pittsburgh Spirit, an indoor soccer team in the United States. This move was part of his exploration of opportunities outside the UK. Later that year, he returned to England to play for Halifax Town, where he made 12 appearances and scored 4 goals. Although his time at Halifax was short, it added another chapter to his diverse playing career. McNiven ended his playing career with a spell at Morecambe.

In addition to his club career, McNiven also had the honour of representing Scotland at the under-21 level. He earned three caps for the Scotland Under-21 team, scoring one goal. This experience highlighted his talent and provided him with the opportunity to compete at a higher level of football.

After retiring from professional football, McNiven transitioned into various roles outside the sport. Initially, he worked as a milkman in St Annes, a job that kept him connected to the community. Later, he ventured into the automotive industry, becoming a second-hand car salesman in Preston. His ability to connect with people and his dedication to his work helped him succeed in this new career. Eventually, McNiven advanced to the position of commercial sales manager, a role that allowed him to utilise his leadership skills and business acumen. His post-football career demonstrated his versatility and ability to adapt to new challenges.

McNiven’s legacy extends beyond his own career. His sons, David and Scott McNiven, followed in his footsteps and became professional footballers. This continuation of the footballing tradition within the McNiven family is a testament to David’s influence and the passion for the sport that he instilled in his children.
