The 18-year-old has had a fine pre-season for the Catalan outfit and topped it off with two goals in last night's Joan Gamper Trophy against Club Leon.
The teenager has been tipped to make the breakthrough at the Camp Nou this season and Enrique is believed to be considering a first-team role for the Spaniard.
"We knew that Munir has the quality, how far he goes depends on him. It is a delight to have the reserve squad we have," Enrique told the club's official website.
Barcelona open their La Liga challenge against Elche this weekend.
