Dr Jonathan Dewhurst dashed to the aid of the spurs supporter who suffered a heart attack at Bristol Parkway Railway Station.
Dr Dewhurst resuscitated the man and waited with him until an ambulance arrived to take him to hospital.
The good samaritan doctor is now keen to find out how the Spurs fan is doing. If anyone knows who the 44-year-old fan is they should call the club on 020 8365 5000 or Nick Evans at the Lancashire Evening Telegraph in Blackburn on 01254 678678.
A Blackburn Rovers fan who helped save a rival fan's life on the way to Sunday's cup final is trying to trace him.
