Spain rounded off their European Championship preparations with a shock 1-0 defeat to Georgia at Estadio Coliseum Alfonso Perez on Tuesday.
The FIFA-ranked world No. 137 stunned their illustrious opponents with a breakaway goal five minutes before half-time as Tornike Okriashvili netted from close range.
Spain's command of the tie was incessant throughout the warm-up clash, and despite good openings for Nolito and Aritz Aduriz, the minnows held on for a well-earned victory.
Manager Vicente del Bosque was hoping to learn more about his squad and possibly gain an insight into his starting XI ahead their venture into Euro 2016, naming David de Gea in goal and handing Real Madrid winger Lucas Vazquez his senior international debut.
The Daily Mail's Adam Crafton believes the Manchester United stopper will be the Spain No. 1 at this month's international tournament:
Spain immediately began to demonstrate their superiority on the contest with long periods of concise ball retention.
Aduriz had the first clear-cut chance of the match with 23 minutes on the clock. Vazquez darted past Giorgi Navalovski down the right wing and sent a perfect cross into the six-yard box. However, the Athletic Bilbao striker arrowed his header off target.
Following 3-1 and 5-1 defeats to Slovakia and Romania, respectively, Georgia's back line did not welcome Spain's continued persistence and attacking intent. At times every member of their team were camped inside their own defensive third in order to prevent the reigning European champions.
Their resilience almost broke on the half-hour mark as Thiago Alcantara struck the foot of the right-hand woodwork, but his effort on goal rebounded away from danger.
The Mirror's European correspondent, Ed Malyon, offered his views on the issues Spain faced:
However, against the run of play, Georgia stole in to take a surprising lead. Jordi Alba was caught in possession on the halfway line by Jambul Jighauri, who darted into the box before unselfishly cutting the ball back to the unmarked Okriashvili eight yards out.
The midfielder made no mistake with the goal gaping to tap it in, regardless of the Spanish players' protestations for offside.
ESPN Spanish football writer Dermot Corrigan highlighted the challenge de Gea was up against in order to clamp down his position between the sticks:
Del Bosque made wholesale changes during the half-time interval, as he brought Andres Iniesta, Hector Bellerin, Koke and Mikel San Jose into the action in place of Thiago, Cesc Fabregas, Sergio Ramos and Juanfran.
Iniesta provided the first attempt on goal of the second 45 minutes, but his well-hit strike from the left of the area bounced wide of the target.
Sergio Busquets and Georgia goalkeeper Nukri Revishvili collided with a sickening blow of heads on 52 minutes, with both players bloodied and flattened after crashing into one another while contesting a loose ball inside the box. Revishvili was eventually forced off with a bandage wrapped around his head, but the Barcelona midfielder surprisingly returned to action despite having his head stapled back together.
Following the lengthy stoppage in play, La Roja continued to dominate the possession statistics, but Georgia's defensive discipline was frustrating the Euro 2008 and 2012 winners.
BBC Spanish football writer Andy West could barely believe the scoreline with time running out:
With 20 minutes remaining in Madrid, Celta Vigo forward Nolito worked space on the lip of the 18-yard box to shoot off target as the Spain attackers were finding space to be at a premium with so many Georgian players kept behind the ball.
Gerard Pique headed off target with three minutes to play in what would prove to be the final chance of note in normal time. Despite the fourth official issuing seven minutes of additional time because of the injury early on in the second period, the 2010 World Cup winners were unable to break down Georgia's resilient defence as they fell to defeat for the first time since March.
Following the full-time whistle, Spain head coach Del Bosque admitted the match did not go to plan as his side were caught out on the counter and then failed to break down their opponents.
Per Corrigan, the experienced boss refused to shy away from reacting to the shock loss at the hands of Georgia:
Despite the embarrassing and unwanted defeat ahead of Euro 2016, Del Bosque played down the impact on his players. Per Corrigan, he said: "This game does not change anything—after a defeat like this, those who did not play are always [seen as] the best."
