He may not feel the pressure, but what I mean more is that people think he might be a much better player than he really is. Chances are really high that he might turn into another Nolito, Cuenca, or any other noteable wingers that the Masia produced.
As already pointed out by Indignado, those players aren't even close to comparable. At Deulofeu's age, both Cuenca and Nolito were messing about in the Spanish 3rd division. Deulofeu, on the other hand, was wanted by just about any top club out there, and his talent is so much more apparent than the two former.
Now, I'm not saying that he's necessarily destined for greatness, but he has so much more going for him than the run-of-the-mill La Masia winger.
