Liverpool manager Jurgen Klopp was left to rue their dire first-leg performance against Real Madrid as his side exited the Champions League after a stalemate at Anfield.
The hosts could not fashion another of their famous European comebacks as, despite registering 15 shots, they managed just four on target and Real goalkeeper Thibaut Courtois was barely tested.
But what really cost them was their performance in the Spanish capital for last week's first leg when their opening 45 minutes was woeful and led to them losing 3-1.
"We started the game really well. We didn't lose the tie tonight, we lost the game in Madrid, it was clear," he said.
"If we had gone 1-0 up it would have been a different game but because of the experience of Real Madrid and their situation we had to chase the game and they controlled the game and had counter-attacking chances themselves.
"With two good performances we would have had a better chance."
Liverpool created enough chances but they were just not clinical enough in front of goal, a failing which has cost them already this season.
"It was uncomfortable for Madrid, we were good, we were aggressive, we played some really good stuff, had massive chances in the beginning of the game," he added.
"If we used one of them, it opens up. They had already struggles, it would have increased that.
"It is a little bit ourselves this year because we had ridiculous games here we should have won, not tonight but in the Premier League, where we just didn't finish.
"Many times Mo Salah finished these type of things. We had many situations and we could have created more because the football we made was better."
James Milner, who started for Liverpool, echoed his manager's sentiments.
"I thought the performance was good and the intensity was good, the desire was good. We won the ball back well and created good chances, but when they came we needed to take them and we didn't do that," he said.
"I think the positive is that we are creating the chances. We've done enough tonight to go through, and I honestly believe that. But if you don't take your chances...If you get the first one then it changes the game.
"It's a disappointing way to end because if we played the first leg with that intensity it might have been a different story. We gave ourselves a mountain to climb with the poor performance in the first leg.
"Ultimately we weren't good enough over the two games. We did everything we wanted to do tonight, except get the two goals - which is the most important thing."
