Everyone deserves a chance.
If Kewell was not ready to be fielded, Benitez wouldn't have risked him on the pitch.
Therefore, Kewell can be termed a "shirker" in the books of Professionalism.
As a human, I may be sympathetic towards him. But if he holds the hope of millions of Pools fans, he is just not on.
He should publicly announced that he is not ready. Period.
The on-going debates about him is more detrimental to him than his non-performance on the field.
