To answer the q that you ask Kewell's best position seems to me to be on the left of midfield but in a very attacking role (people may disagree with me). The Inter rumour has been around for a while and it seems that Leeds may lose him, not good considering the fact that mr Floyd went last year.
EU- passport, he played with the Leeds youngsters but I don't really know, it is not that much of a deal in Britain as it is Spain or Italy.
