Barcelona goalkeeper Marc-Andre ter Stegen admits he's been impressed by Pau Cubarsi.
The teenage defender is due to start tomorrow against Champions League opponents Napoli.
Ter Stegen said: "On the one hand we talk about the footballer and this aspect, at his age he is doing a spectacular job.
"On a personal level, he is a very accessible person, open to improvement and work. He is at the beginning of his career and we hope he continues like this.
"He can improve a lot still. Now it is time for him to play and accumulate many minutes. We hope he improves, he is in a spectacular way and we have to take advantage of him."
