He later moved to Spain, where he played for Real Zaragoza. In 1988, whilst Chilavert played for Real Zaragoza, he stated that "the fans used to freak out" when he would come out with the ball at his feet and "scream at me to get back in goal. I've never stopped to think about what others are saying. I just rely on my abilities. Later on, I started to practice penalties and free kicks until they gave me the job for real". Chilavert admitted to staying behind after training to practice 80 to 120 free kicks, which in his opinion was how he got better.
