At halftime, Celta Vigo were trailing 0–1 at home against Deportivo Alavés after a weak first half in the team's La Liga premiere.
Before the second half, the home team made several substitutions, including a Swedish substitution when Carl Starfelt was replaced and Williot Swedberg came in.
20 minutes later, Swedberg equalized for Celta Vigo, when the 20-year-old turned around with the ball and finished with the outside of his foot in goal.
The former Hammarby player also contributed with an assist when he played forward to Iago Aspas' winning goal (2–1) in the final minutes.
