Amir Khan: 'It's been a tough career'
Amir Khan hopes he may finally be in line for a dream fight with American legend Floyd Mayweather following his return to the boxing ring after over a year and beating Luis Collazo.
The 27-year-old welterweight, from Bolton, has now set his sights on the undefeated world champion but admitted to 5 live's Mike Costello "It's very hard for a British fighter to come and make a mark in America".
He believes he's "very close" to a fight with Mayweather, claiming there's a lot of public demand for it.
