Liverpool winger Harry Kewell has hit back at manager Rafael Benitez after he claimed the Australian's injury status changed from day to day.
Kewell, 26, is angry about suggestions his on-going groin, ankle and Achilles problems are nothing more than an act.
"For anybody to say I'm putting on an act over the injuries is plain ridiculous and wrong," said Kewell.
"Tell me who wouldn't want to finish a Carling Cup final or play in the Champions League?"
Kewell rejected a request from Benitez to play in the European tie at Bayer Leverkusen last week and is currently having treatment in Germany.
The former Leeds star has made just two starts in three months and had to be withdrawn before the hour mark during the Carling Cup defeat to Chelsea in Cardiff.
Kewell's agent Bernie Mandic believes Liverpool have contributed to Kewell's deteriorating condition.
"Harry did the right thing in helping the club through a crisis by putting his body on the line," Mandic told The Sun.
"But there has been no acknowledgement of that by the club. Instead he has been slammed by certain individuals.
"He was told by Liverpool that playing would do no more damage. But the problem has been getting worse. It has caused other issues in his back, groin and hamstrings.
"Some of the information given to the media about Harry's condition has been misinformed or plain dishonest."
Last week, Benitez claimed he was baffled by Kewell's injuries and did not from one day to the next whether he would be fit.
Benitez said: "One day Harry is okay, and the next he says he is unfit.
"We don't know exactly what the problem is. It changes each day. One day he says it's the groin, then it's ankle. Another day he says he can play."
