https://en.wikipedia.org/wiki/Football_in_Greenland

The Football Association of Greenland, founded in 1971, is not a member of FIFA or any of its confederations, but was a member of the International Football Union and ConIFA, secondary governing bodies of association football for nations and sub-national countries that are not FIFA members. Although the Faroe Islands, another dependency of Denmark, is a member of FIFA and UEFA, Greenland is considered part of Denmark for the purposes of international football. However, Greenland have still been fighting to join UEFA and FIFA. The Greenland football association and the Danish DBU entered into an agreement in 2015 to grow the sport of football in Greenland and work towards FIFA and UEFA membership by 2022. With the update of UEFA's statutes to forbid the admission of football associations from non-independent regions, Greenland found their path to UEFA membership closed. They later applied to CONCACAF, but that application was unsuccessful.

Just as well, or Trump would have annexed them by now!
