Answer
The answer is Turkey. When Marc Overmars scored his first goal for the Dutch national team, he was playing against Turkey. Overmars, known for his speed and dribbling skills, represented the Netherlands from 1992 to 2008, earning 86 caps and scoring 17 goals. His first international goal came on September 10, 1992, during a World Cup qualifier match against Turkey in Istanbul, where the Netherlands won 3-1.
