Well. They played Roma, Wolfsburg, and will play City, all 3 with the return leg at home.
We beat Roma 6-1, won vs Leverkusen without Messi (who is better than Wolfsburg) and beat City 4/4 in the CL in back to back season. With that draw, we would have made the final almost surely.
the last 6 return games in knock-out phase of CL will have been played in Bernabeu, that's right all 6 of this & last years CL -> I'm no mathematician, but that seems to be 1.5% chance... And that doesn't take into account the teams they palyed..
Year after year the weakest opponent available and always the return at home. And when they advance they will be the home team. Thats not luck, thats uncle flo's money at work.
