Navas’s various goalkeeping skills are relatively solid, especially his reaction speed, which is top-notch. He often makes magical saves and is relatively calm and calm in the game. He is a player deeply trusted by the coach.

As one of the shining "goalkeepers" at the 2014 Brazil World Cup, Navas may have used the "tennis training method" when training to prepare for the game. Previously, a training video of Navas was leaked in Costa Rica. Navas trained with Spanish tennis player Pablo Andujar. Pablo swung his racket to kick the ball, while Navas was hitting the tennis ball in front of the goal. It is reported that the speed of the tennis ball reached 160 kilometers per hour at that time. In the video, even when faced with tennis balls, Navas's success rate in making saves is still quite high.
