The 19-year-old, who has made six appearances for the Toffees this season, has reportedly been earmarked for a first-team role with Barcelona next season.
"I have played a little less than in Spain, but I am happy there, getting involved little by little. I am working every day and for that, everything arrives," he told Reuters.
"Every game in the Premier League is very nice. There are differences with the Spanish League, of course, but it is football. I'm very happy with the experience."
The Spanish Under-21 international scored 18 goals last season for Barcelona B.
