Commentary from Mike Costello on the 5,000m final in Rio, as Great Britain's Mo Farah won his fourth Olympic gold medal.

The feat meant he became only the second man in history to retain the 5,000m and 10,000m titles.

The 33-year-old won in a time of 13 minutes 3.30 seconds to finish 0.6secs clear of American Paul Kipkemoi Chelimo, who was disqualified along with fourth-placed Muktar Edris of Ethiopia and Canada's Mohammed Ahmed in fifth.

Hagos Gebrhiwet of Ethiopia, who crossed the line in third, won silver, and Bernard Lagat of the United States was promoted from sixth place to bronze.
