I also think he's getting overhyped atm, especially by Barca twitter. He had many impressive plays but also times where he just got crowded out and stifled in duels or tight situations. His tiny stature can actually be a problem because real physical pressure could overwhelm him and he did look that way a number of times especially in the first 30 mins or so he played. The main impressive thing was his involvement and how much he managed to do on the pitch.
The talent and skills are there, people are jumping the gun too early with him though.
