Morocco wants to stage the game in Casablanca at the Grand Stade Hassan II, a huge stadium currently under construction north of the city.
"Spain has proven its organisational capacity over many years. It will be the leader of the 2030 World Cup and the final of that World Cup will be held here," Louzan said late on Monday at an event organised by the Madrid Sports Press Association.
Louzan did not say whether the match would be played at Madrid's Santiago Bernabeu or Barcelona's Camp Nou, the two leading candidates.
Once completed in late 2028, the new stadium in Morocco is expected to hold 115,000 spectators. Morocco's Royal Football Federation (FRMF) President Faouzi Lekjaa last year expressed his wish to see a final against Spain in Casablanca.
However, Louzan alluded to the challenges Morocco faced during its hosting of the last Africa Cup of Nations, including the chaotic scenes during the final between Senegal and Morocco this month.
That match, which Senegal won 1-0, was overshadowed by fan disruptions and player protests that temporarily halted play.
"Morocco is really undergoing a transformation in every sense, with magnificent stadiums," Louzan said. "We must recognise what has been done well. But in the Africa Cup of Nations, we have seen scenes that damage the image of world football."
FIFA and the Portuguese and Moroccan football federations have not responded to requests for comment on the final's location.
FIFA told Reuters last year it was premature to decide the venue for the 2030 final, saying the host city for the 2026 World Cup final was revealed only two years before the tournament. World soccer's ruling body has the final say on where the match will be played.
