John Hartson (born 5 April 1975) is a Welsh former professional footballer who played as a striker most notably in the Scottish Premier League for Celtic. Hartson is currently a pundit for BT Sport.
Hartson also featured in the Premier League with Arsenal and West Ham United as well. He also took part in England’s top flight for Wimbledon, Coventry City and West Bromwich Albion and in the Football League for Luton Town and Norwich City.
Hartson also earned 51 international caps for Wales, scoring 14 goals. After retiring from playing, he held the position of head coach for Wales’s strikers.
In July 2009 Hartson received chemotherapy after being diagnosed with testicular cancer which had spread to his brain. It was later reported the cancer had spread to his lungs and that he remained in a “critical condition” following emergency surgery. The treatment was successful and by December of that year it was reported that cancer had been virtually eradicated from Hartson’s body although he would have more surgery and treatment to come.
Hartson has had a well documented battle with a gambling addiction but since starting to attend GA meetings in 2011 has continued to remained clean ever since.
