Mikel Oyarzabal and Ayoze Perez were on the scoresheet as the unbeaten Roja made it four wins and a draw to pull six points clear of the second-placed Danes.

Luis de la Fuente's side capitalised on a poor pass from Denmark centre-back Jannik Vestergaard to open the scoring as Oyarzabal latched on to a ball from Perez and finished past Kasper Schmeichel in the 15th minute.

Villarreal forward Perez then doubled the visitors' lead in the 58th minute after Dani Olmo turned provider with a defence-splitting pass.

The hosts reduced the deficit with six minutes of regulation time left, as Fabian Ruiz's back pass to goalkeeper David Raya was intercepted by Gustav Isaksen, who had been denied by the woodwork moments earlier, and he slotted into an open goal to set up a tense ending.

But Spain held on for the win and will now face Switzerland in its final group game next week, before taking part in the quarter-finals, scheduled for March.
