Both teams had their chances in a tense opening half, with Dani Ceballos hitting the post with an effort from distance.
And while there were still chances in the second half the game ended goalless.
Elsewhere there was a shock as Australia beat Argentina 2-0, with the latter suffering a bizarre red card to Francisco Ortega. The midfielder was booked for a foul and then quickly shown a second yellow from the resulting free-kick for jostling in the box.
