Paul Gascoigne's agent believes the former England midfielder's life is in danger after he started drinking again.
Gascoigne, 45, appeared to be unwell and trembling at a charity appearance in Northampton on Thursday.
His agent Terry Baker told BBC Radio Five: "He won't thank me for saying but he needs to immediately get help.
"Whatever's happened to him in the five or six weeks since I saw him before Christmas, he is not as well as he has been.
"He's been absolutely fine, he really has, and now he isn't. But I think he knows that.
"His life is always in danger because he is an alcoholic. Maybe no-one can save him - I don't know. I really don't know."
