Gary Walker is a former professional footballer who played as a central defender. He began his career at Tottenham Hotspur, where he made his debut in 1991. However, he struggled to establish himself in the first team and was loaned out to several clubs, including Southend United and Colchester United.

In 1994, Walker signed for Southend United on a permanent basis and became a regular in the team. He helped the club win promotion to the third tier of English football in his first season and was named the club's Player of the Year in his second season.

In 1996, Walker joined Cambridge United, where he spent two seasons before moving to Scunthorpe United. He played a key role in Scunthorpe's promotion to the third tier in 1999 and was named the club's Player of the Year in the same season.

In 2000, Walker signed for Rotherham United and helped the club win promotion to the second tier of English football in his first season. He was a regular in the team for the next three seasons before joining Peterborough United in 2003.

Walker spent two seasons at Peterborough before joining Boston United in 2005. However, his time at Boston was short-lived, and he retired from professional football later that year.

Throughout his career, Walker was known for his physicality and aerial ability. He was also a reliable defender who rarely made mistakes. Despite never playing for a top-flight club, he was a respected player in the lower leagues of English football and was regarded as one of the best defenders of his generation.

After retiring from football, Walker became a coach and worked with several clubs, including Boston United and Gainsborough Trinity. He also worked as a pundit for local radio stations and appeared on television as a football analyst.
