Vitor Roque scored the first goal of his Barcelona career in a 1-0 win over 10-man Osasuna on Wednesday.
The 18-year-old made his sixth appearance for Barca when he came on as a substitute in the 62nd minute.
He got his head on the end of a stylish Joao Cancelo cross just 64 seconds later to put the home team ahead in Montjuic.
Roque was involved in the game's other major incident in the 67th minute when he attempted to sprint away from Osasuna captain Unai Garcia, who grabbed him.
Garcia was shown his second yellow card and then sent off.
Wednesday's win saw Xavi Hernandez's side move five points clear of fifth-placed Athletic Bilbao in La Liga.
But it was far from a perfect night for Barca, who lost Ferran Torres to an injury in the opening five minutes. Torres left the field in tears.
