Mike Williamson is an English central defender who was born in Stoke on-Trent on 8th November 1983. Williamson began his career at Torquay, making his debut as a substitute against Luton on 22nd September 2001. He made five further appearances before joining Southampton in November 2001 for £100,000. Williamson was brought to St Marys as one for the future. He spent the entire 2002/03 campaign playing for the clubs reserve side. The following season he returned to Torquay on loan for two months in September. He made another temporary switch to Doncaster in 2004, but failed to make a single appearance for the Yorkshire club. Williamson spent 2004/05 on loan at League Two outfit Wycombe. He was released by Southampton in the summer of 2005.
Williamson signed for Wycombe on a permanent basis in June 2005. He was a mainstay in the club's defence for the next few years, performing well in League 2. As well as being a competent defender, Williamson chipped in at the other end, scoring a number of headed goals from set pieces. The former Saints man suffered an injury against Mansfield on 24th February 2007 which kept him out for a year. He was a big part of the Wycombe side that topped the League 2 table in the opening months of the 2008/09 season.
On 26th January 2009 Williamson signed a three and a half year contract for Watford. He made his debut for the Hornets the next day in a 3-0 win over Burnley. Williamson enjoyed a very successful start at Vicarage Road, helping to keep the club away from relegation trouble in the Championship. He scored his first goal for the club in a 2-0 win at Blackpool on 21st February 2009.
Williamson started 2009/10 in fine form at both ends of the pitch, netting goals for Watford in wins against Barnet and Nottingham Forest. Towards the end of August 2009 he handed in a transfer request following interest from Premiership outfit Portsmouth. Williamson moved to Fratton Park on September 1st 2009 for a fee of £2,000,000. It turned out to be one of the most bizarre transfers in recent memory. Williamson failed to make a single appearance for Pompey, because of the club's dire financial situation. If he played it would trigger further payments to be made to Watford. It makes you wonder why the deal was done in the first place.
Williamson signed for Newcastle on 26th January 2010 for an undisclosed fee. He made his debut the next day in a 2-0 win over Crystal Palace. Williamson performed well at St James Park, helping the club win promotion back to the Premiership. He featured regularly in 2010/11, helping Newcastle to a mid-table finish in their first season back in the top flight.
