Liverpool striker Robbie Keane has dismissed criticism from Manchester United boss Sir Alex Ferguson.

He was asked if he was aware that Ferguson had admitted his biggest surprise of the summer transfer window was Liverpool's decision to pay Tottenham £20m for their Ireland frontman.

Keane, however, took the question in his stride, answering: "I am very surprised that John O'Shea doesn't play [for Manchester United] every week.

"Football is about opinions. Everyone has their opinions and I respect everyone's opinion."
