In the Champions League it is not true that Real Madrid also has the support of the referees in addition to luck.
He was lucky, there's no denying that, especially on penalties.
It is important to consider the circumstances that can influence the outcome, but i don't think the referees are corrup
The referees can be very good and bad to any team at anytime, so using the referee as an excuse of not wining a match or using them as the criteria for a team to win a match is not right. Just because the officiating of a match does not favour you at all time, that doesn’t mean you won’t get the chance another time when they officiate you another time. They cannot be just 100% as it’s human nature, so referees should not be given too much blame on the outcome of a match already won or loss.
Don't be salty. I guess you have not yet watched the slow replay of Alvarez's penalty. Even aguero has also said it was a double touches. How can you say that Madrid gets helped by the referee? It's solely referee's decision according to the rule.
You're accusing Real Madrid gets helped by the referee. How can they win it 15 times?

I remember when Real Madrid was complaining bitterly about referee’s judgement on their games about being partial in their judgement in most of the matches. They even wanted to drop out of the league and stop playing in the La Liga even when we know they were just blabbering just for referees to be more careful when officiating them. Now that referee was in their favour in this match against Atletico Madrid, we don’t hear them say anything again. When a match officiating favours you, you get to hail the referee and when it doesn’t you make a lot of noise about it.
