Kewell is likely to recover in time for the World Cup but his close friend Djibril Cisse admits he felt sorry for the Aussie as he left the pitch in tears.
"Harry is like a brother to me here at Liverpool, and it was hard to see him really disappointed like that," said Cisse.
"So I went over to get him at the end. I wanted to do my best for him, but it was hard. Three times in a final now he has had to come off. So I am going to do what I can for him."
