Barcelona beat Athletic Bilbao 2-0 on Wednesday to qualify for the Spanish Super Cup final, according to Anadolu Agency.
Gavi, a Barcelona midfielder, scored the opening goal in the 17th minute in the semifinal in Jeddah, Saudi Arabia, as the 20-year-old brilliantly finished near the six-yard box after a low pass from the left.
In the second half, Barcelona doubled their lead at the King Abdullah Sports City.
Gavi sent a killer ball to Lamine Yamal and the 17-year-old forward quickly entered the penalty box to beat Athletic Bilbao goalkeeper Unai Simon in a one-on-one to make it 2-0 for Barcelona.
Chasing a record 15th Spanish Super Cup title, Barcelona will face either Real Madrid or Mallorca in Sunday's final.
The Real Madrid vs. Mallorca fixture will be played Thursday at the King Abdullah Sports City.
