Juan Miranda was happy after the 4-1 Copa del Rey win over Cultural Leonesa on Wednesday, in which he played the full 90.
The left-back showed his good defending and his ability to get forward up the end, even though he will not turn 19 until January.
At the end of the game he said "I enjoyed it like a child," after being given the chance to play in the stead of Jordi Alba.
The Barca B defender said: "We knew that they were a tough opponent, coming to Camp Nou with just a small lead for us and they would press to try and turn that around. They are in Segunda B but they are a dangerous team. We had to take advantage of our weapons and we did that."
Miranda confessed "I am very grateful to the coach and I have to take advantage of these opportunities, but I know that my team is Barca B."
He also congratulated Riqui Puig. "Riqui has stupendous quality and always it's good to see him play, with the first team or Barca B."
