Adrián continued to appear regularly for Deportivo in the 2010–11 season, again as a starter. In the Copa del Rey, the Galicians faced Córdoba CF in the round-of-16: after a 1–1 draw in Andalusia, he scored the 1–1 in the 90th minute of the second leg, taking the match to extra time where he netted two more for a 3–1 win and a spot in the quarter-finals. He finished as the team's top scorer at seven in 36 games, but they returned to the second level after 20 years.
