It is the second consecutive victory for Spain after losing to Sweden in the fourth round, which strengthened its position at the top of the group, with 13 points, four points ahead of its direct pursuit, Sweden, which suffered its first loss in the qualifiers when it fell to its host Greece 1-2.
Spain struggled to win despite its control over the course of the game, and almost conceded a goal against the course of play when Rachani hit a powerful ball from outside the area that passed next to the right post of goalkeeper Unai Simon (15).
Spain waited for the 32nd minute to translate its absolute control into a goal when West Ham United striker Fornals took advantage of a ball from Juventus striker Alvaro Morata inside the area and hit it strong with his left into the goal.
Spain continued its advantage without effectiveness until the 89th minute, when Manchester City striker Torres reassured it with a powerful shot from the edge of the area.
In the same group, Greece at least revived their hopes of competing for second place when they inflicted Sweden’s first defeat in the qualifiers 2-1 and served Spain.
Anastasios Pacasitas (62) and Vangelis Pavledis (78) scored the two goals for Greece, and Saudi Al Ittifaq striker Robin Quaison (80) scored Sweden’s goal.
Sweden’s balance froze at nine points from four matches, while Greece raised its tally to six points in third place, two points ahead of Kosovo.
The group includes Georgia, which is in last place with one point.
