AMIR KHAN was a young, unsigned teenager who stepped onto the British boxing scene and has been there ever since.
Bolton, a boxing legend, became a household name when he won a silver medal at Athens Olympics 2004.
Amir Khan, a British boxing legend, was born in London.
This set him up to have a career full of highs and lows, as well as everything in between.
SunSport looks back at Khan's transformation from Olympic hopeful into a full-fledged star.
2004 Olympic Games
Khan was Team GB’s only representative in Greece for boxing and the nation’s hopes rest on his shoulders.
He did the impossible and lost to Cuban champion Mario Kindelan in the lightweight final.
Khan would revenge the loss one year later in a rare televised amateur match which was seen by SIX MILLION viewers on ITV.
Soon after, he became a professional and was already a star.

Lightweight
Khan became a professional at the 135lb limit (9st 9lb), and quickly rose up the ranks.
He was well on his way to world title honours, until a shocking 2008 loss by unknown Colombian Breidis Preston.
Prescott's stunning knockout in round one was enough to spark the debate surrounding Khan's chin.
Khan returned with two wins at lightweight and then moved up to light-welterweight.
Light-welterweight
His first fight at 140lb (10st division) was against Andreas Kotelnik, a Ukrainian wrestler who was fighting for the WBA title.
Khan was astonished by the speed and agility with which he won the points belt.
Khan would have eight more fights at weight and unify the titles with a win against Zab Judah, an American legend.
Khan gained weight quickly after his defeats to Lamont and Peterson, who failed a postfight drug test.
Welterweight
Khan was able to chase super-fights against boxing legends Floyd Mayweather and Manny Pacquiao.
He failed to win despite having the ring with Devon Alexander, Luis Collazo and Chris Algieri.
Khan lost only one weight against Terence Crawford, the current WBO champion.
Despite being in the same weight class, Khan and Kell Brook were unable to reach an agreement despite years of negotiations.
Middleweight
Khan shocked the boxing world when he signed to fight Canelo Alvarez, a Mexican powerhouse, for the WBC middleweight title.
The fight was actually contested at an actual 155lb (11st), catchweight, 1lb less than the light-middleweight limit.
Khan was nevertheless beaten by Canelo, despite his size and power. Khan was left with a huge right hand and was forced to quit in round 5.
Khan claimed Alvarez had rehydrated to 13st3lb one day after they weighed in. However, he entered the ring only at 11st 2lb. This is a huge difference.
Kell Brook catchweight
They finally reached an agreement to fight as their careers were in the final stages.
Brook was not able to reach the welterweight limit, and this cost him dearly.
Khan suggested a catchweight for Khan of 149lb (11st 6lb), which is just 2lb more than the welterweight.
A contract penalty of PS100,000.000 will be applied for each pound that either fighter could lose.
