Spain's two-year unbeaten run under coach Julen Lopetegui continued with a 1-1 draw against Switzerland in Villarreal on Sunday.
David de Gea's incongruous mistake handed a dogged Switzerland side a 1-1 draw away to Spain in a pre-World Cup friendly.
The Manchester United goalkeeper is regarded as being among the world's finest but he spilled a shot from reported Arsenal target Stephan Lichtsteiner, presenting Ricardo Rodriguez with a tap-in.
Spain were producing a commanding display to assert their status as one of the pre-tournament favourites prior to De Gea's out-of-character error in Villarreal.
Vladimir Petkovic's determined Swiss outfit had kept four consecutive clean sheets but they were undone by a goal out of the top drawer from Alvaro Odriozola in the 29th minute.
