Chris Coleman knows he will never get Serbia out of his system no matter what happens in Belgrade on Sunday night.
Coleman is a national hero these days and recently picked up an OBE at Buckingham Palace after guiding Wales to the semi-finals of Euro 2016.
But Coleman admits that a 6-1 defeat away to Serbia in September 2012 was the lowest point of his five-year reign and will never leave him.
It will be another tough Eastern European test for #Wales. #SRBWAL #TogetherStronger https://t.co/nnxI13EEhk
