Harry Kewell, the out-of-contract Liverpool winger, is determined to prove Rafael Benitez wrong, after being released by the Anfield club.

The 29-year-old, who made 139 appearances for Liverpool, has failed to recapture the form he showed at Leeds United since his move, although his time on Merseyside has been marred by a combination of injury and inconsistent form.

Despite that, the Australia international remains confident of his abilities insisting that he has nothing to prove to anyone - except Benitez.

"The one person I'd like to show is my old manager," Kewell said. "I didn't get a chance to show him a lot of what I could do and it would be great to show him what I was capable of doing. I didn't put my hand up to be injured. It's one of those things you have to go through in your life and it's a shame."

Kewell also played down reports claiming he has already agreed a deal with Portsmouth.

"Apparently my agent did it [a deal with Portsmouth] while he was on the plane coming over to Australia, so I don't know how he's done that," Kewell said on a trip to his homeland.

"But I've never shied away from going abroad. I've never shied away from playing in the Premier League, I've never shied away from playing anywhere. My options are open and we'll see what happens."
