Barcelona's 17-year-old DeRo previously made his official first-team debut against Real Sociedad. He started in that league game and played 45 minutes.
Dero: "Thank you very much. Well, that experience was unique and to be honest, it was something I've been working towards since I got here. I'm really happy, to be honest, going through it with a lot of excitement, very happy.
"Making your debut in front of our fans makes it even more special, but like said, making your debut in this shirt, whether it's in the Champions League, the league or the cup, I think is always a very special thing.
"Well, I think I'm a player with good dribbling ability, good decision-making ability and a certain quality, I would say that.
"I think La Masia does a great job and you can see the results reflected every year. But for me it was very special and it helped me and instilled values in all our players who came up to the first team. It was really a wonderful time at La Masia. "
