OOC: Let me preface this by saying thanks for showing interest and I hope you'll still want to get involved in football role-play. I think you're perhaps not understanding how international football operates or what these rankings mean.
The world rankings above are just an estimate based on the results of various international matches that take place throughout the course of a season (both competitive tournaments and qualifications matches and official friendlies) rather than a league system. National teams typically only meet to train during breaks in domestic club competition or prior to major tournaments (like the World Cup). For this reason, it's unrealistic to suggest that a national team would be training three days a week during the season, the players would be training with their domestic clubs during this time and wouldn't be free to meet with the national team.
Once again, glad you're interested in the role-play but just some advice about how it all functions.
