All five former Champions League winners were put into the same half of the draw on Friday, setting up a possible semifinal pairing between Cristiano Ronaldo and Lionel Messi. Real Madrid, Juventus, Barcelona, Chelsea and Bayern Munich ¿ who have combined to win 26 European Cups ¿ will whittle down one side of the draw to reach the final on Aug. 23 at the Stadium of Light in Lisbon. The other side will see three-time finalist Atlético Madrid face Leipzig and Paris Saint-Germain meet Atalanta. Leipzig and Atalanta are newcomers to this stage.

The single-leg quarterfinal matches will be played on four straight evenings from Aug. 12-15 to start a mini-tournament without fans in Portugal. The semifinals are scheduled for Aug. 17-18. Four quarterfinalists are still to be decided, all involving the former champions. Juventus trails Lyon 1-0 ahead of their round of 16 meeting next month in Turin. The winner of the two-leg series will play either Real Madrid or Manchester City in the last eight. City won 2-1 in Spain in February.
