Niko Kovac's men need a win in the clash against Mexico on Monday to set up a last 16 encounter with either Netherlands or Chile.
Rakitic, who has agreed to join Barcelona this summer, has warned his side to be wary of Mexico's quality as they search for the three points needed to qualify.
"Of course, they have a really great team. Also in the defence and in the attack but I think that Mexico also played really strong football," the 26-year-old told reporters.
"They have a good idea and know to attack, they have everything really perfectly prepared and again it will be really hard for us but we want to go through like Mexico too and for that we will have to work.
"I hope that the Mexican players have to think about our team so we can make the perfect game because we need to be ready."
Rakitic has earned 64 caps for Croatia since making his debut in 2007.
