I've been playing around on the editor on FM22 and created an AFC/OFC Nations League competition, similar to the UEFA Nations League competition, only with more of a regional divide (and one less divisional layer).
The 46 Asian (AFC) and 11 Oceania (OFC) FIFA members would compete together in a three-division AFC/OFC competition run every two years, with relegation and promotion between the divisions, and a four-team finals tournament to decide the overall winner.
Division One (16 Teams)
The top 16 ranked AFC/OFC nations will compete in Division One, drawn into four groups of four teams. Each team plays the other three teams in their group home and away (total 6 fixtures). The top team in each of the four groups progresses to the end of season tournament (played in Qatar) to determine an overall champion. The bottom team in each of the four groups is relegated to Division Two for the following campaign.
Teams- Iran, Japan, South Korea, Australia, Qatar, Saudi Arabia, UAE, Iraq, Oman, Uzbekistan, China, Bahrain, Jordan, Syria, Palestine and Kyrgyzstan.
Division Two (20 Teams)
The next best 20 teams from AFC and OFC will compete in Division Two, drawn into four groups of five teams, split geographically into two groups from the West and two groups from the East. Each team plays the other four teams in their group once (total 4 fixtures), each playing two home games and two away games. The top team in each of the four groups is promoted to Division One, and the bottom team in each of the four groups is relegated to Division Three.
Teams- (West) Lebanon, India, Kuwait, Yemen, Thailand, PR Korea, Afghanistan, Tajikistan, Turkmenistan, Maldives (East) Vietnam, New Zealand, Philippines, Solomon Islands, Hong Kong, Malaysia, Indonesia, Taipei, Myanmar, Singapore.
Division Three (21 Teams)
The next best 21 teams from AFC and OFC will compete in the third and final division, drawn into three groups of five teams, and one group of six teams, again split geographically into two groups from the West and two groups from the East. As in Division Two, each team plays the other teams in their group once, playing two games at home, and two games away (apart from the one group containing six teams where a draw is made to determine who plays the extra home fixture). The top team in each of the four groups is promoted to Division Two.
Teams- (West) Cambodia, Nepal, Macao, Laos, Mongolia, Bhutan, Brunei, Bangladesh, Pakistan, Sri Lanka (East) New Caledonia, Papua New Guinea, Tahiti, Fiji, Vanuatu, American Samoa, Cook Islands, Samoa, Tonga, Guam, Timor Leste.
