The Reds had a disappointing night in Madrid and will require a momentous comeback at Anfield if they are to progress to the next round. Seconds after Marco Asensio's goal, Brych brushed away Liverpool's appeals for a foul by Lucas Vazquez on Mane.
Klopp made his feelings known after the game. "The situation with Sadio – what the ref did tonight I don’t understand," he said. "For me that was something personal because he dealt with the situation with Sadio, which was a clear foul, like he was a diver or whatever. From that moment on whenever Sadio went down he didn’t get anything. "
"That is not right. That is what I told him after the game, that I thought he was unfair with Sadio. That doesn’t change anything at all. He didn’t lose the game. We were not good enough to get a better result, but in these moments you need just an ‘ok’ ref. That would have been enough.”
The German was also extremely upset with his side's performance and added, "If we want to go to the semi-finals we have to earn the right to do so and we didn’t do that, especially in the first half.
"The only good thing I can say about the game, apart from the goal, is that it is only the first half of the leg. We just didn’t play good enough football tonight to cause Real Madrid more problems. I thought it would have been possible but we have to show it in the next game. We made it too easy for them."
Liverpool host Real Madrid at Anfield next Wednesday, and will have to score at least two goals to ensure they make it to the Champions League semi-finals.
