Bale confirmed his decision in a statement on Instagram, saying he has taken an “opportunity for a new adventure."
The former Southampton, Tottenham, Real Madrid and Los Angeles FC forward called time on a 17-year playing career, in which his honours included three LaLiga titles, the Champions League five times and the Club World Cup on three occasions.
Bale’s final appearance came in 3-0 defeat to England as Wales were knocked out of the group stage of the World Cup in Qatar.
