Milan survived a first round fight, defeating Celtic (eventual champions of that year's Scottish Premier League) 1–0 on aggregate after an extra time goal by Kaká. Milan would then go on to defeat Bayern Munich 4–2 on aggregate (2–2 at San Siro and 2–0 at Allianz Arena) to reach the semi-finals, marking the third consecutive, and fourth time in five years, that Milan has reached the final four of the competition. The first leg of the semi-final was played against Manchester United at Old Trafford. Manchester scored early on a goal from Cristiano Ronaldo, but Milan answered back through a brace from Kaká, ensuring a 1–2 lead at half-time. United would ultimately prove victorious, however, due to two second-half goals from striker Wayne Rooney. This match was regarded by the media and UEFA President Michel Platini as the greatest match in recent memories. The second leg of the semi-final was played at San Siro on 2 May, where Milan played a near-perfect first-half, taking a 2–0 lead into the break with goals from Kaká and Clarence Seedorf. A 78-minute goal by Alberto Gilardino sealed the victory for the home side.
