Do u believe in the conspiracy of the refree backing barcelona in UEFA?

There have been alot of talk about this issue in the past 4 years. The game against Chelsea was one the most miserable refree you could witness in your life. As well as what Mourinho said in the 1st leg in Santiago. The PEPE red card and for the last four 4 classicos madrid have been given the red card. Now nobody doubts Barcelona capabilities they have fantastic players. But you always see they have that extra push from the officials to win the game. what your opinions about it?
