Can categorically state that the foreign ACFC players do footballing work in the community. Zubi's my mate's goalkeeper coach, and I believe the entire squad ran a few months of courses at Auckland Grammar for 13-15 year olds
While I am sure the ACFC players do more than "no coaching", it is highly unlikely that the money they get for coaching is reflective of the coaching that they actually do, and more to do with their selection in the ACFC team.
