"It's so hard to play against a team that only wants to close you down, but these are the types of games that win you a World Cup", said defender Dani Carvajal after Diego Costa's rebounded goal took them level with Portugal on top of Group B. Since then they have won six and drawn three games against non-European countries.
Wednesday's results mean Spain and Portugal now sit joint-top of Group B on four points apiece.
Instead it was Morocco, who lost their Group B opener 1-0 to Iran, who were the more aggressive side, missing half a dozen clear scoring chances and the Portuguese conceding far too much space.
Both Greece and Kosovo cancelled scheduled friendlies and sportswear giant Nike refused to supply the players' boots due to USA sanctions.
Iran's win over Morocco in the first match made this group a bit messier than expected.

Costa, who scored twice in a 3-3 opening draw with Portugal in Sochi, courted controversy early in the Group B encounter when he stepped on the toes of Iran 'keeper Ali Beiranvand.
Ziyech whistled another set-piece just over the crossbar from 25 yards as the minutes ticked away and both Nordin Amrabat and Benatia fired over with better chances, but there was to be no last hurrah for Morocco as their hopes of making the knockout stage slipped out of reach.
Costa claimed his third goal of the tournament in the 54th minute at Kazan Arena but the striker hardly knew about it, the ball deflecting off his knee from an attempted clearance by hapless Iran defender Ramin Rezaeian. Of those 20 wins, 10 have been by a single goal and most of the others were against weaker opponents.
After a hard-fought win against Peru on Saturday, Denmark know that a win will book them a spot in the next round. "But having said that, we're not playing against any weak teams".
