In October 2015, there was talks regarding Mosley challenging WBO light middleweight champion Liam Smith (21-0-1, 11 KOs) to take place later in December, in a fight which would see Mosley making his UK debut at the age of 44. Mosley was said to be excited about the potential fight and told World Boxing News, "I might take the fight with Liam Smith, but they say we must have a rematch clause." He went on to say that if Smith wanted a rematch, he would have to take it within eight weeks or after October 2016, due to plans already made for early 2016. By the end of October, Mosley pulled out of the negotiations as he would not accept the rematch clause. In a statement he said, "There's no way I should have taken that fight for less than a million and I took it damn near for free, but they blew it over an immediate . It's strange." Mosley believed Smith should have been more grateful in fighting him.
