Football legend George Best has died at the age of 59.

The former Manchester United and Northern Ireland icon finally passed away at 12.55pm this afternoon after a lengthy battle with ill health.

Best had an alcohol problem for much of his adult life and underwent a liver transplant in 2002 after years of heavy drinking.

A spokesman for the Cromwell Hospital in west London confirmed: "After a long and very valiant fight Mr George Best died this afternoon in the intensive care unit at Cromwell Hospital.

"The thoughts of all staff at Cromwell Hospital are with Mr Best's family at this time."

Born in Belfast, Best played for United from 1963 to 1974 and his finest hour came in 1968 when the Red Devils became the first English club to win the European Cup.

Best made 180 goals in 474 appearances for United and also won two league championships, in 1965 and 1967.

A statement from United read: "George Best was one of the greatest footballers of all time.

"Naturally athletic, tough, confident and blessed with genius, his career was one of the brightest stars of its generation. His gifts were legendary.

"For the goals, the audacious dribbles and all the wonderful memories, Manchester United and its legions of fans worldwide will always be grateful.

"We feel a deep sense of loss but his spirit and his talent will live on forever."

Bobby Charlton, a director at Old Trafford and a team-mate of Best's during his time at the club, said: “Manchester United's glorious history has been created by people like George Best.

"Anyone that witnessed what George could do on the pitch wished they could do the same. He made an immense contribution to the game, and enriched the lives of everyone that saw him play. It is a very sad day.

"Football has lost one of its greats, and I have lost a dear friend. He was a marvellous person and my thoughts are now with his family."

The club will open a book of condolence tomorrow morning at Old Trafford.

The Irish Football Association led the mourning in Best's native Northern Ireland, for whom he made 37 appearances and scored nine goals.

IFA chief executive Howard Wells said: "This is a sad day for football. George was a complete one-off with a natural talent rarely seen since.

"I had the privilege of entertaining him when I worked in Hong Kong and I also saw one of his early internationals for Northern Ireland, in 1964. He had this incredible balance, speed and grace. He was the best I had ever seen."

IFA director of coaching Roy Millar added: "He was an icon of Northern Ireland football and he will be remembered for his performances for Northern Ireland and Manchester United.

"He was the most talented footballer Northern Ireland has ever produced and he was a world star."

Best's funeral will take place in Belfast on Friday.
