Kompany said: "Another good performance. The only thing we miss is another goal.
"I always want to reflect on the game, but the goal we concede, it's just not a foul.
"The lad just slides over after he tries a pirouette. The referee's in the best position on the pitch. He just falls over and we get a set-piece against us and concede a goal.
"As much as I want to look at my team, it does seem to be the trend of this season. These moments cost us.
"It just keeps happening. I think in the last game I was definitely not right in the way I reacted, I don't want to do that. I react calmly now. But I still see the same pattern.
"I get it, we all make mistakes, but it's just too much, it's too easy. He was in the best decision. It's absolutely clear it's not a foul.
"I think I have the right to be frustrated, and seeing as I'm expressing it in the right way, I think it's fine.
"But now we have to move on and focus on the next game."
