Paul Gascoigne is reportedly heading back to the UK after a successful stint in rehab.

Paul 'Gazza' Gascoigne is reportedly heading back to Britain after spending a month tackling his alcohol addiction in a US rehab clinic.

Friends of the 45-year-old football icon insist he is back on track after his stint at the Cottonwood Clinic in Arizona, and claim he has vowed to quit drinking for good.

"We're just delighted that Paul's back on track and coming home, where he can get back into his routine of doing the things he enjoys - without the booze getting in the way ever again," a source close to the star told the Sun.

Following the former England midfielder's very public breakdown at a charity event in Northampton in January, celebrity pals including Chris Evans, Alan Shearer and Alan Sugar banded together to help raise the funds needed for his treatment.

During his shocking Northampton appearance, the star mumbled stories and swore repeatedly in response to questions from his agent Terry Baker, who was interviewing him on stage.

At one point Gascoigne apparently mumbled: "I've been on a whisky diet". One onlooker claimed that it looked like he was "dying in front of our eyes".

Shortly afterwards, his ex-flatmate Shane Abbott released video footage of Gascoigne mumbling, groaning, and struggling to stay conscious.

He claimed that Gascoigne was hooked on a lethal cocktail of drink and drugs which sometimes included litres of gin, 15 cans of Stella Artois, anti-depressant Valium pills and cocaine on a daily basis.

Gascoigne was apparently rushed to intensive care amid fears alcohol withdrawal could have triggered a major organ failure just hours after he was admitted into rehab, the Sun reported.

Upon hearing news of his impending return to the UK, fans and celebrities flocked online to offer their messages of support.

Man United striker Wayne Rooney tweeted: "My best wishes are with him and I hope he can get himself out of this."
