Robben completed his move to Real Madrid on a five-year deal on 22 August 2007, with the transfer fee reported as £24 million (€35 million). He made his debut on 18 September as a substitute for Raúl during a Champions League match against Werder Bremen, which Real Madrid won 2–1. His league debut came on 23 September, this time as a substitute for Royston Drenthe in a 1–1 away draw against Valladolid. On 10 February 2008, Robben scored his first goal, this time at home in a 7–0 victory against Valladolid. Robben proved crucial for many Real Madrid matches, making his famous runs down the left wing, and quickly became a first choice for the left midfield position, making 28 appearances during his debut season and scoring five goals. Real Madrid won the league title with some games to spare, and were already the champions of Spain when they played their arch-rivals FC Barcelona on 7 May 2008. The Barcelona players formed a guard of honor as the Madrid team came onto the pitch at the Santiago Bernabéu, and Robben played an important part in Real Madrid's subsequent 4–1 victory, scoring the champions' second goal.
