Liverpool manager Jurgen Klopp was lost for words after watching his team fall to defeat at Nottingham Forest.
Taiwo Awoniyi returned to haunt former club to earn the hosts only their second win of the season and hault the Reds' growing momentum.
Both Roberto Firmino and Virgil van Dijk were guilty of missing glorious chances, and Forest keeper Dean Henderson denied the centre-back with a stunning save at the death.
"The performance I can kind of explain, the result not to be honest," Klopp told BT Sport. "I never saw a game where one team has four or five no-brainers from a set piece where we have to finish it off.
"The way they defend we were perfectly prepared for that. We had to put the game to bed to be perfectly honest. The goal we conceded was a big mistake from us. We lose the ball and give them the free-kick and this can happen around set pieces.
"Apart from that, all the chances they had we gave them. We had to make really late changes and in general a lot of changes and it's a game you have to win doing the right stuff again and again and again and we didn't. That's why we stand here and have lost the game.
"Result-wise we should have showed consistency today. We could have had it by finishing situations off."
Asked if he can congratulate Forest on the win, Klopp replied: "Giving a team six clear chances after a set piece I'm not sure where I should put the praise to be honest. They are a great team and Steve is a great manager but for us today we have to win here and we didn't, so credit to Nottingham."
