-pLiverpool winger Harry Kewell says he's sick and tired of people having a pop at him over his recent performances.
The Aussie ace says the criticism isn't fair because he's only 70 percent fit and he adds that if there wasn't an injury crisis at the club he would be laid up resting. Instead of sitting out crucial games, Kewell insists he's playing purely to help the manager.
Kewell said: "Ideally I'd have taken a break because it's obvious I've been struggling to produce anything near my best for a while now. But the boss has terrible injury problems and I have to do my bit for the team.
"At this level of football if you can't run freely it's difficult, if not impossible, to deliver. I've been playing it a bit safe on the pitch because I know I can't produce the intensity people expect.
"It's been difficult and I've been the target for a few people who have rightly said I'm not up to scratch. What disappointments me is some of them have hammered me without acknowledging that I've not been fully fit. Everybody has a time when things go badly and this is my turn.
"I don't hide from the fact I've been below par. But after the Arsenal match I felt no pain for the first time in a while in my left ankle and that's encouraging.
"I haven't been training properly because of the injury (sustained against the Solomon Islands in October) and it's hindered me. My endurance and ability to perform at the level I know I'm capable of just hasn't been there.
"I'm confident I'll turn the corner soon because my confidence is still there and I'm now going to be able to get fitter.
"It's a game of slender margins, I've come close to scoring lately for both Liverpool and Australia and if one had gone in I'd have been treated a lot differently.
"I'm my own harshest critic. People expect something special from me and I have to me to live up to that."
