Juan Camilo Zuniga, the player who ended Brazilian superstar Neymar's World Cup participation four years ago, announced his retirement on Wednesday.
The 32-year-old Colombian wing-back was involved in a collision with Neymar in a quarter-final match at the Brazilian World Cup in 2014 that resulted in the forward suffering a broken vertebrae.
Neymar's World Cup was over and without their talisman Brazil suffered the humiliation of losing 7-1 to eventual champions Germany in the semi-finals.
After himself suffering two injury-plagued years, an emotional Zuniga said: "Today I'm thinking about my future, my family. I'm stepping aside so that tomorrow, when I want to to run around in the park with my children, I'll be able to do so." The wing-back began and ended his career at Medellin club Atletico Nacional but spent much of his career in Italy, notably a nine-year spell at Napoli.
