Amir Khan remains hopeful of facing Floyd Mayweather in the American's final fight in September but admits he will not "chase" a potentially career-defining bout with the unbeaten welterweight.

Mayweather had confirmed his intention to retire following the final fight on his Showtime Television contract, following his unanimous points victory over Manny Pacquiao in Las Vegas.

Khan has previously furiously campaigned for the chance to face Mayweather but the Briton continues to be overlooked by the 38-year-old, who is searching for an opponent to end his career against later in 2015.

And after facing Chris Algieri on 29 May, Khan will reignite attempts to face Mayweather but he is unwilling to pursue the five-weight world champion.

"There has been a lot of talk that it will be September when Mayweather is back in the ring again," Khan told BBC Radio 5 Live. "I am not going to chase it like I used to chase it. I am going to keep fighting and if it comes, it comes."

Khan, who is due to observe the fasting period of Ramadan in June added: "I want to focus on Chris Algieri right now but I really think it can happen.

"I am spending more time in the gym before and after training camps, so when I join the camps I am half-way there. I am happy at this weight and feel comfortable. I think I can do the September fight if it happens.

"It gives me enough time to do my Ramadan and fasting, and then go into training camps for nine to 10 weeks."
