Yes Daniel and Diego were involved with futsal and set-up the Samba Futsal Academy in Wellington. I know a South American coach who applied for the assistant coaches position at Phoenix before it was given to Greenacre and he is still waiting on a reply from the club!
Football is football and futsal is futsal. For me two different sports. I agree futsal can help in the development of young players and should be encouraged but a tactically its a different game especially for outdoor coaches to grasp.
