Amir Khan has raised the prospect of an all-British fight against Kell Brook, as his hopes of a match with legendary fighter Manny Pacquiao diminish.
The 28-year-old from Bolton had hoped to be Pacquiao's final opponent.
"It just seems Pacquiao doesn't want to fight me," he told BBC Sport, naming Danny Garcia, Lamont Peterson and Sheffield's Brook, 29, as alternatives.
He later tweeted: "Pacquiao fight could still happen if he signs the contract, but I'm also looking at other options."
Former two-time light-welterweight world champion Khan beat Chris Algieri in their bout in June and felt he was close to facing Floyd Mayweather - but the multiple world champion opted to fight Andre Berto in his final bout instead.
Seven-weight world champion Pacquiao, 36, would be an alternative high-profile bout for Khan, who has won 31 of his 34 fights, but he is not confident of a deal being agreed.
"We've been trying for the last few months to get it done," he added. "I don't want to be in the same position as I was with Mayweather, when he promised me the fight and I was waiting and waiting and it never happened.
"He probably just doesn't feel confident and thinks it will be a tough fight for him."
But he also mooted a meeting with IBF welterweight champion Brook, who has called on his compatriot to get in the ring.
"A rematch with Danny Garcia could be an amazing fight for me - it is a fight where I want to prove myself," said Khan. "I know I am a better fighter than he is and I just made a mistake when I fought him the first time.
"When I fought Lamont Peterson I know I won the fight but didn't get the decision, but a fight with Kell Brook could happen as well - he is one of the top guys who we would be looking at."
