Gordon Taylor, the Professional Footballers' Association chief executive, vowed his organisation will not be giving up on Paul Gascoigne.
Gascoigne, who has spoken about alcoholism problems in the past and was sectioned five years ago under the Mental Health Act, appeared to be unwell and trembling at a charity appearance in Northampton on Thursday.
His agent, Terry Baker, says the 45-year-old had been drinking and needs immediate help, suggesting Gascoigne's life is "always in danger". Taylor is adamant that his union will continue to give Gascoigne as much support as possible.
"We have tried to support him throughout all his problems with rehabilitation at various clinics, with medical help," Taylor said.
"We are in regular touch with him and have been again.
"We go one step forward and two back at times and this is just the situation. It is unfortunate, but we try to keep going."
The former Manchester United goalkeeper Peter Schmeichel has called on the PFA to "step up" their efforts to help Gascoigne, writing on Twitter after watching the video of the appearance: "This is not fun watching. Gazza needs help. Come on PFA & Gordon Taylor, time to step up."
