Spain's fringe players will be given a chance to stake their claim for a starting place in the World Cup knockout stages when the team face Saudi Arabia on Friday.
Luis Aragones looks set to rest his entire first-choice XI with Spain having already secured their berth in the next phase with a maximum six points from their opening two Group H matches, scoring seven goals in the process while conceding just one.
Real Betis winger Joaquin, an important member of the team that reached the quarter-finals four years ago in Japan and South Korea, is among those who will play against the Saudis in Kaiserslautern.
"We want to play the best possible game, this is still a World Cup game," said Joaquin.
"Even though we have already qualified for the second round, we want to finish the group stages with another win.
"We will not play thinking that we are already through but we will enjoy the opportunity that the coach will give us."
Joaquin, who played 33 minutes in their 3-1 triumph against Tunisia, is hopeful of getting more game time.
"From a selfish point of view, I want to play all the time," he said.
"But the most important thing is that we are ready to play when the coach needs us."
A point against the Saudis will be enough to see Spain finish top of their group but they have yet to find out who their last-16 opponent will be, with France, Switzerland and South Korea all fighting for the two qualifying slots in Group G.
"France are not at their best but they are still France," Joaquin continued.
"Regardless of the rival we meet it is still going to be difficult.
"We just have to worry about ourselves. If we maintain our level it's going to be difficult for any team to beat us."
Saudi Arabia have a mathematical chance of advancing to the next round but they need Ukraine to lose to Tunisia while they must beat Spain convincingly.
There is, however, an additional incentive for Marcos Paqueta's men to beat Spain.
Bin Fahd Abdulaziz, Sultan of Saudi Arabia, has pledged to double the team's prize money of they can beat Spain and clinch their first win of the tournament.
"I don't know if this will be my last World Cup but I hope to do better in the next game if it is," said forward Sami Al Jaber, who has yet to find the back of the net.
"Being here in this World Cup is a good experience for the young players in the squad and I hope they benefit from this and take this team higher."
