Park Chu-young played his first game in Spain's La Liga on Saturday. He came on as a substitute for Iago Aspas in the 71st minute when his new club Celta Vigo were down 2-1 at Valencia's Mestalla Stadium.
Park got several touches of the ball but no goal-scoring chances as the team ran out of steam and recorded their third loss of the season.
Celta Vigo now have three points from four games.
