With just over four months to go until the start of the finals in South Africa, the 59-year-old's preparations are running smoothly and he promised few surprises.
"The squad is settled and, bar two or three players, everyone knows who is going to be on the list," Del Bosque told students at the Complutense University of Madrid.
"The way we play is well-known, we have our style and tactics and all we are missing now are the photos to complete the picture. After that we just need to put the accent on the little details."
Players such as Sevilla winger Jesus Navas and Barcelona forward Pedro are in the running for the undecided places, as is Racing Santander teenager Sergio Canales who has burst on the scene in recent weeks.
"His sudden appearance is fantastic," Del Bosque added. "His age (18) does not rule him out for the World Cup but there is a lot of competition in his position (attacking midfield)."
The former Real Madrid coach gave his backing to South Africa as hosts.
"There are many doubts over South Africa's ability to organise the event but I predict a great success, as they have already proved with the Confederations Cup and the World Cup draw," he said.
"It's a country that needs it and has our support. The World Cup is going to leave a great economic and social legacy because football brings people together."
