La Roja are looking to win a record third-straight European Championship when the tournament gets underway in France on Friday between the hosts and Romania
Koke believes Spain's shock loss to Georgia in their final warm-up friendly for Euro 2016 will not affect the two-time defending champions heading into the tournament.
A first-half goal from Tornike Okriashvili saw Georgia claim a 1-0 win over Spain at the Coliseum Alfonso Perez in Getafe on Tuesday.
The loss came less than a week after they defeated South Korea 6-1 courtesy of doubles from Alvaro Morata and Nolito.
However, Koke insists the Georgia defeat will have no effect on double-defending champions Spain as they contest Group D alongside the Czech Republic, Turkey and Croatia.
