The former Newcastle, Tottenham and Rangers star has long battled with alcohol addiction and he returned to a clinic for treatment this week, the Daily Star has reported.
The paper said that the 45-year-old had been "bingeing on gin for breakfast and spending his days fishing while drunk," and that he fell into a river while angling.
"He’s in a proper mess. It’s been terrible to watch," a source told the paper.
"Quite often he will go to a local shop in Bournemouth to buy a bottle of gin late morning.
“He is existing on a diet of gin, lager and vodka.”
A spokesperson for the ex-player, affectionately known as 'Gazza', told the paper: "We can confirm that Paul Gascoigne is currently in an addictions clinic, receiving the best possible care and attention that he requires.”
Gascogine played 57 times for England between 1988 and 1998 scoring 10 goals for the national team.
