The 19-year-old has burst onto the first-team scene at club level, starring in pre-season before scoring against Elche in his La Liga debut and again being named in the team for the win over Villarreal last weekend.
The attacker's early-season form has earned him a promotion to the Spain Under-21 squad, having previously played at under-19 level and Del Bosque has hinted the final step up the international ladder is not far away for the player who remains eligible to play for Morocco at international level.
"The first step has been taken. He came to the teams below and now he has been called for the Under-21s," Del Bosque told Mundo Deportivo.
"We cannot and will not put any obstacle in his way before we summon him for the seniors.
"We incorporated Bojan when he was just a newcomer to the first team at Barcelona and thought ‘If he is very good, why wouldn’t we?’ We will do the same here."
Under-21 coach Albert Celades, who will be using Munir in the upcoming fixtures against Hungary and Austria, is confident that the starlet will be a big part of Spain’s future.
He said: "Munir has a fantastic attitude. We will take care of him and make him feel comfortable.
"We believe in him for the future of Spain."
