2004–05 UEFA Champions League knockout stage
The knockout stage of the 2004–05 UEFA Champions League featured the 16 teams that had finished in the top two of each of the eight groups in the group stage and lasted from 22 February to 25 May 2005. The knockout stage followed a simple, single-elimination format, with the ties in each round (except for the final) being played over two legs, with whichever team scored the most goals over the course of the two legs progressing to the next round. In the case of both teams scoring the same number of goals over the two legs, the winner would be determined by whichever team scored more goals in their away leg. If the teams could still not be separated, a period of extra time lasting 30 minutes (split into two 15-minute halves) would be played. If the scores were still level after extra time, the winner would be decided by a penalty shoot-out. As in every season of the competition, the final was played as a single match at a neutral venue, which in 2005 was the Atatürk Olympic Stadium in Istanbul, Turkey.
The final pitted four-time European Cup winners Liverpool of England against six-time winners Milan of Italy. After Milan went 3–0 up in the first half, Liverpool scored three goals in the space of six second-half minutes before winning the match 3–2 on penalties in what has since become known as the "Miracle of Istanbul".
