Senegalese referee Malang Diedhiou is hanging up his whistle after a career that has seen him take charge at the Fifa World Cup, Confederations Cup and the Olympics.
Diedhiou, 45, a Senegalese customs inspector, was involved in four matches at the recent World Cup in Russia.
He was in charge of the Group games between Costa Rica and Serbia and then hosts Russia against Uruguay, and the knockout match between Belgium and Japan.
His final assignment was as the fourth official for the third place play-off between Belgium and England,
"I could have continued and push on until the 2019 Nations Cup, but our association would have struggled to prepare the next generation," he told Senegalese news agency APS.
"By retiring now, it gives our referee body an opportunity to prepare a younger person who is ready to officiate at the next African Cup of Nations.
Four years later he was handed group stage games at the 2016 Olympic Games in Rio.
He served as a Video Assistant Referee (VAR) official at the 2017 Fifa Confederations Cup in Russia, alongside Gambia's Bakary Papa Gassama, before he was named as one six African referees to officiate at the 2018 World Cup.
