Match preview
Will the 2021 runners-up book their ticket to another UEFA Nations League Finals tournament?
After four matchdays, Spain currently sit top of Group A2 with eight points to their name.
La Roja only drew their first two games in this group, but come into this one following back-to-back wins.
First, Pablo Sarabia got the only goal of the night at Stade de Genève.
Then, Carlos Soler and Sarabia again were on target, this time in a 2-0 victory over Czech Republic at La Rosaleda.
So, Luis Enrique’s side are one point clear of Portugal, with those two meeting at Estádio Municipal de Braga on Tuesday.
Spain could have first place sown up before then, if they win and Portugal lost in Prague simultaneously.
This game will be la Roja’s first in Zaragoza since defeat to Greece in 2003, so will it be worth the wait for the local fans?
Switzerland meanwhile were pointless in this group after Spain’s victory in Geneva on matchday three, and seemingly doomed to relegation.
However, in the last outing, Haris Seferović's goal after just 57 seconds downed Portugal; the fastest goal in Nations League history.
So, Murat Yakın’s men are just one point below Czech Republic, who they welcome to St. Gallen on Tuesday.
However, if the Swiss are beaten here and the Czechs beat Portugal, Rossocrociati will be relegated to League B for the first time ever.
It is all to play for Estadio La Romareda, but will Spain be simply too strong?
