The first semi-final was played between the winners of Groups A (Benfica) and C (Porto), while the second  was played between Group B (Braga) and D (Sporting CP) winners. Groups A and B winners (Benfica and Braga, respectively) were designated as the "home" teams (for administrative purposes) in their semi-final clashes as was the winner of the first semi-final in the final.
