A video has been released showing the disappointment written all over the face of Kell Brook after an ultimately underwhelming performance in Saturday’s super-welterweight fight with Michael Zerafa.

In Sheffield, the Yorkshireman won a unanimous point decision against his counterpart but was clearly disappointed with the result after failing to knock out the Australian.

On the night, he was ultimately looking to send a compelling message to Amir Khan, who he believes is dodging a grudge match. However, the performance itself sent a very different message to the former unified light-welterweight world champion.

After the win, Brook met with Billy Joe Saunders to discuss the fight. Saunders was clearly trying to reassure Brook that any win is a good win and he should be proud of a comprehensive performance.

“A win is a win. And you battered him.”

In spite of this, Brook wanted more than the fight and suggested that it should have been over way before the end of the fight.

“I should have ***** laid him out there in a couple of rounds,” claimed Brook who looked as though he had just experienced a crushing defeat.

Despite this, Saunders again looked for the positives and suggested that this fight is both a learning curve and an opportunity to lead Khan into a false sense of security.

“In hindsight, that might have done you a favour. For one you know for next time. And two, he [Khan] might think- yeah I’ll fight him now.”

Hearing this, Brook instantly looked happier and agreed with Saunders. “He [Khan] might run towards me now, after that performance.”

Brook showed a hint of a smile in an otherwise bleak recording. He was quick to disregard that the 12 rounds were a good thing and made it clear that his heart was set on the stoppage.

His new trainer, John Fewkes, tried to keep his man's spirits up but Brook knew he had been under par.

We'll have to just wait and see whether it was enough to tempt Khan into agreeing a deal though.
