Barcelona youngster Marc Guiu scored his first Barcelona goal on his debut for the club, shortly after coming on.
The teenager netted the match winner in what was a very difficult game against Athletic Bilbao.
The 17-year-old came on in the 78th minute, and a minute later his first involvement led to a goal.
Joao Cancelo trolled the overjoyed teenager immediately after the game.
“You have to buy us a dinner. You have to buy us a dinner at McDonald’s,” Joao Cancelo told 17-year-old Marc Guiu after the final whistle against Athletic Club.
