Former English national team midfielder Paul Gascoigne believes he was on the brink of death when he slipped into a coma while receiving treatment for alcohol addiction in the United States.

The 45-year-old Gascoigne flew back home on Saturday, a month after being admitted to the intensive care unit of a hospital in Phoenix following a relapse in his long-running struggle with alcoholism.

Gazza, who starred in the 1990 World Cup, told Sunday's editions of The Sun that his lungs and heart seized up but now insists he will not drink again.
