Angry Kell Brook is urging Frank Warren to do all he can to get Amir Khan to face him.
Warren has already put forward a multi-million dollar offer to Khan to step up to welterweight and taken on undefeated British rival Brook.
And the Yorkshireman was left fuming when Khan turned down the offer, saying that he used to beat him up in sparring.
"Believe me, it was always the other way around," said Brook.
"I couldn't believe it when I read what Khan had been saying - may be all those punches he took against Maidana have had an affect on his memory.
"We used to do a bit together when we were both in the amateurs, and I showed him up every time we got in the ring together.
"Amir's come on a bit since then, but then so have I.
"I'd seriously love it if Frank Warren could get this fight on because we could settle it once and for all.
"I watched Khan's last fight against Maidana.
"Fair play to him because he soaked up some punishment to hold on to his title.
"But Maidana showed that Khan's chin hasn't improved much since he went to Freddie Roach. He can take a shot better, but he still gets clipped and hurt.
"I feel that I've got the power to take him out of there. One clean shot on his chin is all that I need to land."
