Spain forward Ferran Torres scored a first career hat-trick as his side crushed helpless Germany 6-0 at home on Tuesday to storm into the final four of the Nations League.

The schellacking in Seville was the Germans' worst ever loss in a competitive match, with keeper Manuel Neuer conceding six goals in a match for the first time in his career with club or country.

Goals from Alvaro Morata, Ferran and Rodri gave Luis Enrique's side a convincing 3-0 lead at halftime, while Ferran struck again early in the second half and completed his treble with a classy finish.

Substitute Mikel Oyarzabal tapped in the sixth goal in the 89th minute to adorn an incredible Spain display and deepen four-times world champions Germany's misery.

"It's definitely a bitter defeat. It's very, very disappointing for us all. I am part of the team. We talk about the we. We screwed this up together. Our body language was disappointing, we did not communicate on the pitch. We should have talked more," Neuer said after the match.

The victory saw Spain finish top of League A4 with 11 points after six games, while the Germans, who only needed a draw to progress to the final phase, came second with nine.
