Format
The draw for the first knockout round took place on 15 December 2006 and involved each of the top two teams from each group in the group stage. The winners of each group were paired up with the runners-up from another group.

Each knockout round tie consisted of two-legged matches, home and away, in which the team with the higher aggregate score progressed to the next round, with the exception of the final, which was played over just one match at a neutral venue. In the event that the two teams' aggregate scores were tied, the team that scored more goals in their away leg progressed to the next round, with extra time and a penalty shoot-out being used if the tie was still level.
