Chile finished second in Group B behind Netherlands, setting up a meeting with Brazil tomorrow evening.
The coach told FIFA.com: "One thing I can absolutely guarantee is that we're going to play a fast game, regardless of the opposition.
"Every match is different, but our attitude and approach stay the same. Our strategy, tactics and physical fitness will dictate the pace of the game, and we'll be looking to attack.
"We were the ones who went for the win. We played with intensity but we couldn't find a way to break down a team that just defended and shot from distance."
Chile beat Australia and Spain in the group stages before being beaten by the Dutch side in their final match.
