National team friendlies may be played each Friday at 8 PM (Hattrick Time) by national teams that do not have a World Cup match scheduled at that time. These matches are pretty much equivalent with the friendlies that clubs play midweek.
In order to schedule a friendly, the national team coach must either challenge another team or accept a challenge in a manner similar to club coaches. The process is slightly different however, as the system does not notify the national team coach of a challenge. National team coaches must send messages or HT-mails to each other to set up the friendly.
The challenger is able to choose which arena the friendly should be played in. Any arena may be chosen, including neutral ground. There are no fees for arena rental.
