Spain were held to a 1-1 draw by Switzerland in the first of their two warm-up games for the World Cup.
The Spanish, who thrashed Argentina 6-1 in March, had threatened to win at a canter when Alvaro Odriozola’s 20-yard volley put them ahead in Villarreal.
But the Swiss, who were second best for long periods, capitalised on a mistake by Spain keeper David de Gea, Ricardo Rodriguez tapping in an equaliser.
Spain plays Tunisia on Saturday, while Switzerland take on Japan on Friday.
Despite fielding an experimental line-up, without any of the Real Madrid players that won the Champions League final just over a week ago, Spain remains unbeaten under head coach Julen Lopetegui.
The 51-year-old who replaced Vicente del Bosque in 2016, has won 13 and drawn six of his 19 games in charge, to retain the longest current unbeaten streak in international football.
Eight years ago Switzerland sprung a surprise by defeating Spain in Durban during the opening game of the 2010 World Cup in South Africa.
And this match followed a similar script. Spain dominated possession and chances but ultimately were denied the victory that their performance merited.
Fielding three of the survivors of the squad that recovered to win their next six matches to become World Champions for the first time, the Spanish rapidly took control.
Two of that trio, Andres Iniesta and David Silva orchestrated the play and Thiago Alcantara and Silva both spurned chances to score before Odriozola’s goal.
While the substitutions of Silva and Iniesta – around the hour mark – loosened Spain’s grip on the game, they were close to mustering a late winning goal with Nacho Fernandez hitting the post and heading wide.
The Spanish now tackle England’s Group G opponents Tunisia on 9 June in Krasnodar, their base for the finals this summer.
Lopetegui’s side begins the tournament against Portugal on 15 June – the first time the nations will have met since the Euro 2012 semi-final, which Spain won on penalties.
The 2010 winners then play Iran on 20 June before completing their Group B schedule against Morocco on 25 June.
Switzerland remain rank outsiders
For most of this encounter, it was all about containment for Switzerland who rarely had the ball for long enough to trouble Spain.
However, they remain obdurate opponents with goalkeeper Yann Sommer’s fine display typifying a defiant defensive effort.
Switzerland now faces fellow finalists Japan in Lugano on Friday in readiness for their opening Group E fixture against Brazil on 17 June.
The Swiss, sixth in Fifa’s world rankings but 100/1 outsiders to lift the World Cup, will then take on Serbia on 22 June and Costa Rica on 27 June.
