Amir Khan remains hopeful of facing Floyd Mayweather in the unbeaten American's final professional fight in September despite his commitment to observe Ramadan.
Mayweather has one fight remaining on his Showtime Television contract and is expected to bow out of boxing later in the year despite signalling an intention to hand Manny Pacquiao a rematch in 2016.
The 38-year-old's intention to retire in September had seemingly all-but ruled out Khan from facing Mayweather prior to his exit from the sport, with the Muslim fasting period of Ramadan running from 18 June to 16 July.
With Mayweather likely to schedule the 49<sup>th and final fight of his career in mid-September that would give Khan less than three months to physically ready himself for the bout, however, the former Olympic silver medallist is confident he has sufficient time to prepare.
"I'm not ruling out fighting in September because it's possible that it could happen," Khan said.
"Mayweather only fights in mid-September and Ramadan will be a little earlier this year, which helps. It gives me enough time to get the training done. So it can happen in September."
A unanimous points victory over Pacquiao saw Mayweather extend his unbeaten record to 48-0 in Las Vegas and attention has already turned to who will be his final opponent later in the year.
Khan has campaigned for several years for the opportunity to face Mayweather and the Brit says that while the five-weight world champion impressed in defeating Pacquiao there remains areas of weakness.
"Mayweather looked great, he did what he had to do to win the fight, his accuracy was nothing but the best," Khan added ahead of facing Chris Algieri on 29 May.
"Mayweather is very skilful and patient and tries to make his opponents make mistakes. His work rate dropped tremendously because of his age.
"There were a few things there that I'd not seen before. When he takes a good shot he does panic.
"The only way to catch Floyd is with speed and explosiveness, which Manny had, but Manny didn't use that enough in the fight."
