Costacurta began the 2004–05 Serie A season winning his fifth Supercoppa Italiana after Milan defeated Lazio. Milan would finish the season in second place in a closely fought title race against Juventus. Milan would also suffer a huge disappointment in the UEFA Champions League. Milan reached the 2005 Champions League final in Istanbul as heavy favourites over Liverpool. At half-time, Milan were leading 3–0, but Liverpool made a second half comeback, scoring three goals to tie the match and send it into extra time. Liverpool ended up winning the title in the resulting penalty shootout in what became known as "The Miracle of Istanbul".
