Liverpool boss Jurgen Klopp was left frustrated after their 3-1 defeat to Leicester City.
Mohamed Salah's 67th-minute strike gave the Reds the lead before James Maddison equalised with a 78th-minute free-kick.
Leicester were in front three minutes later when a mix-up between Alisson and debutant centre-back Ozan Kabak allowed Jamie Vardy to score in an empty net.
Harvey Barnes fired in a third five minutes from time.
Klopp began, "We conceded a goal, a really tough one to take, it was a turning point in the game on VAR. I have seen it and when they stop the situation it looks a clear offside - that's it. The second goal is a misunderstanding, we said they need to get used to each other and they were fine for 75 minutes, it was a really good game. On the pitch we were the clear dominant side. We had chances and then we concede two goals.
"We were much too open at that moment and that is not OK. Alisson had a super game and then at that moment he came out, I didn't hear him shouting.
"The turning point was the first goal, We changed too much with one goal, that's the criticism for us. We didn't react well."
The German later reflected: "It was a clear game that we should win. We played good football, dominated possession, took the game out of Leicester but apart from that we were really top in the game. We scored a goal, could have and should have scored more, whatever. Everything fine and then penalty, free-kick, offside, not offside, goal. That had a proper impact. That is something that has to change. The first goal for me is offside. The difference is we think it's an objective thing but it's not.
"Three players offside for Leicester but it was decided to take another moment in the game. That is how it is. The second goal is a misunderstanding obviously. It is a situation where we should shout and I didn't hear anyone shout. It is not that cool. The third goal I really don't like. We are so open. I cannot accept. That was it. The performance for 75 minutes or so was outstanding then we lost 3-1. That shows what a tricky situation we are in."
On James Milner's injury, he added: "Hamstring. Hopefully it is only a little bit but we did not want to take the risk."
