Khan to Brook: You've still proved nothing
Amir Khan has told Kell Brook he still has plenty to prove, despite a three-round demolition of Hector Saldivia on Saturday.
Brook is now the No. 1 contender for Devon Alexander's IBF welterweight crown, and has also expressed a desire to face Khan.
However, Khan - who has lost his last two fights - does not feel his fellow Brit is worthy of his attention.
"Well done Kell," Khan tweeted. "Did what he had to. Time to move up in game. He's been saying this for the past 10 fights. Before you think of fighting me or Ricky [Hatton], PROVE yourself (against someone in the top 50)."
Meanwhile, Ricky Hatton has also raised doubts over the quality of Saldivia, who had only been beaten twice before stepping into the ring with Brook.
"Made up for Kell, good confidence-boosting performance," Hatton tweeted. "I never saw him struggling tonight to be honest. Saldivia had only boxed once outside of Argentina, two losses both stoppages in first and fifth round, and not against anyone of note.
"That's not the point though. Perfect fight following the Carson Jones fight. I wish him all the best in his world-title fight. I think he can beat Alexander."
