Frank Warren says the British public have lost interest in Amir Khan's boxing career following his prolonged absence from the ring.
Khan last week announced a three-fight deal with Warren's rival U.K. promoter Eddie Hearn and will have his first fight in nearly two years against an opponent yet to be announced on April 21.
Khan (31-4, 19 KOs) 31, boosted his profile in the U.K. by appearing on the television series I'm a Celebrity...Get Me Out of Here! which averaged between eight to ten million viewers every night for two weeks.
But Warren says Khan still needs to convince fight fans he is a serious contender again.
"He came to us and asked if we were interested and they said they had the fight with [Manny] Pacquiao," Warren told ESPN. "I offered him to fight Bradley Skeete, and he didn't come back.
"He got badly knocked out in his last fight and people have lost interest. I know he's been in the jungle but that's not fighting.
"Realistically we will see what he has got left in his next fight. They said they are looking for a tough opponent, so they should fight Bradley Skeete. But I know they won't."
Khan's ring return -- his first fight on British soil for five years -- will come on the same night as Carl Frampton's featherweight encounter with Nonito Donaire in Belfast.
"It's ridiculous they are having Amir's fight on the same night as Carl Frampton in Belfast," Warren told ESPN.
"But our fight is a real fight between two quality operators but Khan will be fighting a stiff."
