Would going back to the lot during repeated testing in reality!
Juventus - Barcelona, Paris SG - Galatasaray, Real Madrid - Dortmund and Bayern - Malaga. These are derived from testing couples made in Nyon, Switzerland, just 24 hours before the start of official lottery draw for the Champions League quarterfinal. You remember that couples 1/8 final, came out real well a few days later, after the first test, which was a very rare case or 1/1000 cases could occur.
Look on Friday morning from 12.00, whether repeated these couples or not, but we have witnessed two big matches, Juventus, Barcelona and Real Madrid - Dortmund.
