He was noticed at a young age and stood out through his talent and versatility. Emmers could do it all. Behind the strikers, on the right wing or as a centre back, he did well in any position. That was a disadvantage as well, as Emmers did not have one defined position. He was also plagued by injury during a large part of his career. He came back from injury every time, showing he had character as well. He played with the Red Devils at the 1990 and 1994 World Cup.
