On 23 August 2004, União de Leiria reached the UEFA Intertoto Cup final with Lille. After getting a 0–0 in France in the first leg, the whole city thought it would be possible for the club to win a European competition. However, in the second leg, after another 0–0 draw at their home stadium, the team would lose the game in extra time by 0–2, mostly due to the excessive fatigue. For the history, it was the first Portuguese team to reach the final of this competition.
