Kell Brook has trolled Amir Khan on Twitter after laughing off his claims that he was chasing him for a fight.The two British boxers clashed in the ring on Saturday night after Khan defeated Phil Lo Greco inside 40 seconds at Liverpool's Echo Arena.Khan told Brook that he was "chasing" the Sheffield-born fighter for an all-British clash, but Brook took to social media to taunt Khan over what he saw as false threats.Speaking to Sky Sports, Brook said he is "hungry for blood," but doubts whether Khan would actually agree to a showdown."He didn't have any eye contact with me when I got into the ring," Brook told Sky Sports. "He said 'I only signed with Eddie [Hearn] to get the fight with you, I'm running to you', and then he turned around and ran away!"He says he's running to me, well Amir - I'm here."Brook is not getting his hopes up for a possible fight at Wembley, though."I don't think he fancies it. He can see in my eyes that I'm a possessed man. I'm hungry for blood. He knows that I'm coming to bring it. I'm no Lo Greco, I'm the Special One."I'm going in there to do some damage."Brook admitted that if the fight was to go ahead at the home of football, it would be a career highlight.

"It's what dreams are made of."

"It would be a dream to box at Wembley. I'm sure he'd love that the same way as me. When our careers are over it is going to be great to look back and tick that box.

"It would be bigger than Bramall Lane, I have to say that. Fighting down at Wembley in front of all those people, it doesn't get any bigger."

For now, though, it's clear that Brook needs more than a few idle threats from Khan if he is going to take his challenge seriously.
