Kewell is currently recovering from a foot injury he picked up at the World Cup. The Aussie doesn't yet know when he'll be fully fit again but is determined to be a better player when he does finally recover.
"No question - I'll come back stronger, quicker and fitter," said the Liverpool number seven.
"I've been out for a long time and I'm hungry to come back into it - that's what I'm really looking forward to.
"I can walk around now, but I have to be very, very careful. It's going to be a couple of weeks before I can do anything.
"I'm in a bit of pain now, but expect to be fine in a couple of days."
