https://www.fifa.com/news/the-week-in-numbers-x5831 says: "4 is how many goals the Falepapalangi family contributed for Tonga club Lotoha'apai United in their OFC Champions League encounter against American Samoa's Pago Youth. Tonga U-20 international Tuia scored a hat-trick, but a second-half goal from his father Pua made the feat truly exceptional." In the qualifying group of 4, every club beat every club below them. Lotoha'apai United had 1 win and 2 losses to finish third, when 2 clubs advanced. American Samoa, Cook Islands, Samoa, and Tonga were labeled "developing" and got 1 club in the Qualifying Round. The other 7 countries got 2 clubs in the Group Stage, which begins on 10 February. The Wikipedia pages for World Cup 2014 Qualifying and World Cup 2018 qualifying said American Samoa, Cook Islands, Samoa, and Tonga started before the other teams "based on FIFA World Ranking and sporting reasons." "Sporting reasons" is vague, and this is the first time I've seen Wikipedia use the terms "developed" and "developing" for OFC. https://en.wikipedia.org/wiki/2019_OFC_Champions_League says the groups are: A: Hienghene Sport (New Caledonia), Toti City (Papua New Guinea), Tefana (Tahiti), and Malampa Revivors (Vanuatu) B: Lautoka (Fiji), Central Sport (Tahiti), Henderson Eels (Solomon Islands), and Morobe Wawens (Papua New Guinea) C: Erakor Golden Star (Vanuatu), Team Wellington (New Zealand), Ba (Fiji), and Kiwi (Samoa) D: Solomon Warriors (Solomon Islands), Auckland City (New Zealand), Magenta (New Caledonia), and Tupapa Maraerenga (Cook Islands) Each group will be single round-robin hosted by the club listed first. The top 2 in each group advance to the Quarterfinals. The Quarterfinals and Semifinals will have two legs. The Final will be one game on 12 May.
