Here is the facts, Gonzalez is a Liverpool player but will remain at his club until next season as Liverpool cannot apply for another work permit for him this season. But in January we can say we want him loaned out to a club in the top flight in spain so he gains better 1st team experiance before he comes to us. Then when the season finishes in Spain Gonzalez will be able to apply for Spanish nationality or passport, thus meaning he will not need a work permit to play for us next season but as these applications for nationality can take upto a few months, he will be givin a temporary work permit till hes application for Nationality is fully processed.
So there you have it, Gonzalez will not be seen in a red shirt till next season.
Once he gets his Spanish passport or Nationality, Chiles status in world football will no longer affect him or who he plays for.
