The reigning world and European champions only needed a point to be sure of winning Group I ahead of France and goals in either half from Alvaro Negredo and Juan Mata assured them of all three against Georgia in Albacete.
It may not have been the most emphatic of victories but Navas feels it was mission accomplished nonetheless in a match that could have proved a potential banana skin.
The Manchester City winger said in AS: "We went out looking for the win. Any opponent looks to make it difficult for you and the team have stayed calm. The team have deserved it.
"We had to be very focused throughout the game and keep our heads. We've gone out with a very good attitude and it was important to go for the win."
The match was a special one for Barcelona midfielder Andres Iniesta, who was born near Albacete, and he said on Telecinco: "I've felt very strong emotions; the family, the warmth I've received for returning here...For me there couldn't have been a better place to have secured our place in Brazil."
