The Real Madrid midfielder saw a low shot from 20 yards fumbled into the net by substitute goalkeeper Kiko Casilla, who was making his debut.It was a friendly of little quality, with Bayern Munich forward Thomas Muller limping off through injury in the first half.Spain debutant and Celta Vigo forward Nolito went closest for the hosts, seeing a 20-yard shot turned away by goalkeeper Ron-Robert Zieler.Germany had lost their three previous encounters against Spain, including the Euro 2008 final and the World Cup 2010 semi-final.Del Bosque, who has been Spain boss since 2008, saw his side knocked out of the World Cup in the first round in Brazil and a defeat to Germany caps a miserable year.Neither side looked threatening for much of the match with both restricted to long-range efforts.But, in the end, an error from Espanyol's Casilla proved decisive for the the top-ranked team in the world.Spain were previously unbeaten in the seven matches they had played at Celta Vigo's Balaídos stadium.Bakudaily.Az
