Amir Khan believes the boxing public has lost interest in a potential domestic showdown with fellow former world champion Kell Brook.
Fans have been waiting for several years for this fight to happen.
Brook has been inactive since winning a tougher than expected decision over Michael Zerafa last December. He was scheduled to fight last month as part of the undercard to Anthony Joshua vs Andy Ruiz, but he withdrew from the card.
The fight appeared to be within reach in early 2018, when Khan signed a multi-fight deal with Eddie Hearn, who also works with Brook.
Hearn mapped out a plan where both boxers would see action in at least two fights in 2018, before facing each other in early 2019.
But Khan made a decision to take a pass on Brook, and he instead challenged WBO welterweight champion Terence Crawford.
Khan lost to Crawford by TKO in six rounds, but came back earlier this month with a demolition of undersized foe Billy Dib.
Now Khan is steering his attention to a potential clash with WBA champion Manny Pacquiao - who captured the belt last Saturday from Keith Thurman.
He feels the fight with Pacquiao is now a much bigger event when compared to a grudge match with Brook.
“I don’t think it [the appetite for the Brook fight] is there anymore. Normally, I’d be walking around the streets and people would be talking about that fight, but now, people aren’t talking about that, they are talking about the Manny Pacquiao fight," Khan said to The Evening Standard.
“People have lost interest in that fight against Brook. There are rumours he’s retired, he’s not retired, I don’t know what he is doing with his career to be honest with you - I’m ready to let it go by, I’m not bothered about it.”
