Gary Lineker played alongside Paul Gascoigne for Tottenham and England:
Former Manchester United goalkeeper Peter Schmeichel has urged the Professional Footballers' Association to help Paul Gascoigne, who is struggling with alcoholism and depression.
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."
