Alvaro Morata and David Silva were among the scorers as Group G leaders Spain beat Liechtenstein 8-0 in their latest World Cup qualifier.
Having beaten Italy 3-0 on Saturday, Spain led 3-0 inside 16 minutes in Vaduz through goals from Sergio Ramos, Chelsea’s Morata and Isco.
Manchester City midfielder Silva added a fourth before Iago Aspas made it 5-0.
Iago set up Morata’s second then scored another of his own before Max Goppel’s late own goal completed the rout.
Spain top Group G by three points and have improved their goal difference to 29, 17 better than second-placed Italy, who were 1-0 winners over Israel on Tuesday.
Ciro Immobile’s 53rd-minute header proved enough to take the points.
That win all but guarantees them a play-off spot as their advantage over third-placed Albania – who were held to a 1-1 home draw with Macedonia – is six points and their goal difference 11 better with two games to play.
