Spain will have to win in Portugal if they are to reach the Nations League Finals after suffering a shock 2-1 home defeat to Switzerland in Group A2 on Saturday.

As Portugal cruised to a comfortable 4-0 win over Czech Republic, Luis Enrique's side failed to make the most of their superiority in Zaragoza and slumped to a first defeat since the 2021 Nations League final loss to France.

Spain had great difficulty converting possession into a goal threat, at no point in the first half looking likely to cancel out Manuel Akanji's opener.

Marco Asensio did inspire Jordi Alba's equaliser early in the second half, but an Eric Garcia own goal almost instantly had them playing catch up again and a second equaliser never materialised.

Despite their dominance of the ball, Spain struggled to carve out chances and were behind in the 21st minute as Akanji met Ruben Vargas' corner with a header that found the top-right corner.

The only other first-half shot on target for either team arrived just before the break, Unai Simon forced to keep Xherdan Shaqiri's effort out at his near post after the winger's incisive run.

It took 55 minutes for Spain to muster an accurate attempt and it brought the equaliser, with Alba hammering home after Asensio released him at the end of a brilliant solo run.

But the visitors quickly restored their lead – Garcia ultimately knocking into his own net following Akanji's flick-on from another Vargas corner.

La Roja played most of the final 30 minutes camped in Switzerland's half, but their only clear opportunity saw Yann Sommer get down to thwart Carlos Soler and seal victory in stoppage time.
