Former Wales international John Hartson has admitted on Twitter that despite beating testicular cancer in 2009 and winning a whole host of trophies during his playing days, winning his battle with a gambling addiction is the biggest achievement of his life.
Hartson made 146 appearances for Celtic, scoring an impressive 88 goals during his five-year spell in Glasgow.
The 39-year-old also played for Arsenal, West Ham United and West Brom before hanging up his boots in 2007.
And despite being 3 years 20 months and 20 days gambling free, Hartson still attends GA (gambling anonymous meetings).
Another good constructive GA meeting tonight. 3 years 2 months and 20 days clear of Gambling for me.. Biggest achievement of my life.

When speaking to the BBC in the summer about his addiction, he admitted it all went wrong when he was a football apprentice at Luton Town and he first dabbled with slot machines.
And as Hartson made his way up the football ladder, his addiction worsened – costing him thousands of pounds every month.
Hartson won three SPL titles, two Scottish Cups and a League Cup during his time at Celtic Park and despite leaving the club in 2006 , he remains a popular figure with the Hoops support.
And it comes as no surprise given his inspirational character.
