Costa Rica have amazed the world after holding off teams as powerful as England and Italy. Now, Los Ticos want to surprise the Netherlands.
Coach Jorge Luis Pinto has done a fantastic job with this side, which have qualified for the quarterfinals for the first time ever after defeating Greece in the penalty kicks.
Los Ticos play with a 5-4-1 system, which allows them to defend tightly, while they take advantage of Bryan Ruiz and Joel Campbell's speed and dribbling skills.
However, the quarterfinals will not be easy, especially because Louis van Gaal is one of the best strategists in world football.
He proved it against Mexico, when he changed his usual 3-5-2 formation to a 4-3-3 that ultimately helped him to tilt the scale in his favor.
Let's take a look at the key battles of what promises to be a very interesting game.
