Answer
The answer is Scotland. Salinas netted his maiden international goal for Spain in a friendly match against Scotland on September 21, 1986, in Gijón. The encounter marked his second appearance for "La Roja" and saw him come off the bench in the 72nd minute to replace his compatriot Emilio Butragueño. Spain emerged victorious with a 3-1 scoreline, and Salinas' goal contributed to sealing their triumph over the Scots.
