Axel Andreas Jacob Andersen Byrval (13 March 1875 – 1957[1]) was a Danish amateur football player and manager.
Born in Copenhagen, Byrval started playing football with Boldklubben Frem.
[3] He participated in at least one international game for the Danish selection, against a German team in Hamburg.
[4] Although it was a de facto international organized by the Danish Football Association (DBU), the game is not a sanctioned Denmark national team match, as DBU did not register games as official until the 1908 Summer Olympics.
He managed the Danish team to victory in his first eight games until October 1915, including 8–0 and 10–0 defeats of Sweden.
