Carl Froch: How reluctant boxer became The Cobra

BBC Sport takes a look back at the career of four-time world super-middleweight champion Carl 'The Cobra' Froch after his decision to retire aged 38.

Froch, who went from being a nervous Nottingham amateur to king of the ring, says he will look back on career with "great satisfaction and great pride".

A post-war record crowd of 80,000 people crammed into Wembley Stadium last summer to see Froch retain his super-middleweight crown with an eighth-round knockout of compatriot George Groves.
