National team

Amat made his international debut at the age of 17 in 1995 before being selected for the Atlanta Olympics in 1996. That year, Spain won silver with Amat playing alongside legends such as Juan Escarré and Javier Arnau.

After competing for Spain in both the Sydney 2000 and Athens 2004 Olympics, he won another silver medal in Beijing 2008. He was also part of the Spanish team at the 2012 Summer Olympics.

The striker won his first major title with the Spaniards at the 2004 Champions Trophy in Lahore. Arguably Amat's finest hour came in the final of the 2005 European Nations Cup. With Spain trailing Netherlands 2–1, Santi Freixa grabbed an equaliser with less than three minutes to go. The stage was set for Amat, who produced two goals in less than a minute to seal a 4–2 victory, giving Spain a title that had eluded them for 31 years.

Amat also scored a memorable golden goal at the 2006 World Cup when he brilliantly flicked the ball over the South Korean goalkeeper to claim the bronze medal for Spain.
