Gavin Williams

Hereford United

Williams started his career as a YTS player at Hereford United having previously trained with Cardiff City. He made his first team debut at the age of 17, as a substitute in the 3–0 FA Cup victory over Sittingbourne. He made twelve more appearances that season and scored his first goal against Dover Athletic in the Conference. By the 1998–99 season he was a first team regular playing in a variety of positions in midfield and up front. He was to spend five seasons at Edgar Street, notably scoring a wonder strike against Swindon Town in the 2001–02 FA Cup second round.

Yeovil Town

At the age of 21 he moved to Hereford's rivals Yeovil Town for the 2002–03 season, having rejected a new contract offer at Edgar Street. Hereford received a £22,500 fee for their leading goalscorer plus a 25% next sale clause, which earned the Bulls a further £62,500 in 2004. At Huish Park he was an integral part in the squad which in that season gained promotion to the football league for the first time, scoring six goals, the same season in which his team reached the sixth round of the FA Trophy. He also won the Player of the Year award for his club, an ever-present rock in the midfield.

West Ham

It wasn't long before West Ham United decided to swoop for him, purchasing him in December 2004 for £250,000. But his last act in his last game for Yeovil was to be sent off. He made his West Ham debut on Boxing Day 2004, coming on as a substitute against…

After representing Wales Semi-Pro in 2002, Williams made his international debut for Wales on 17 August 2005, featuring as a second-half substitute in a 0–0 draw with Slovenia at the Liberty Stadium, Wales. He made his second appearance for his country on 16 November 2005, again featuring as a substitute in a 1–0 loss to Cyprus at Tsirion Stadium, Cyprus.

On 27 May 2016, after the resignation of Jenkins, Williams was appointed manager of Merthyr Town. In January 2021, Williams decided to leave his role as manager of Merthyr Town.

Williams' younger brother Lewis is a rugby union player. Gavin's son, Jay, is also a footballer, who played for the Fulham F.C. Academy.
