Luis Suarez has opened up about the effects the damaging 4-0 defeat to Liverpool had on him, going as far as saying he wanted to 'disappear from the world'.
Leading 3-0 thanks from the first leg after a Suarez strike and a Lionel Messi double, Barca completely fell apart in the second leg.
Divock Origi and Gini Wijnaldum bagged braces to send Jurgen Klopp's side into a second consecutive Champions League final and inflict more European misery on Barcelona.
It was the second successive year that they bottled a Champions League second leg, having beaten Roma 4-1 at home in the quarter finals last year before being beaten 3-0 away.
The humiliating loss denied Barca a sixth Champions League title and Suarez was a broken man as a result.
"The days after back in Barcelona were the worst moments of my life and career along with the 2014 World Cup, I wanted to disappear from the world," he told Fox Sports, via The Mirror.
"I didn't want to take my children to school, everyone could see I was in a very bad way, I had days I didn't want to do anything, they were very difficult moments."
Barcelona should have been out of sight in the first leg when Ousmane Dembele spurned an incredible last-gasp chance at the Nou Camp and they missed a number of clear-cut chances at Anfield.
But Liverpool caught them completely by surprise, with Suarez admitting he did not foresee such a collapse.
"I didn't see it because we are Barcelona and we thought we'd have two or three chances to score, but we became nervous, we gave stupid passes away, we didn't show the right attitude," the Uruguayan added.
"When the first goal came we didn't know how to react, we knew we had really messed up. After the game in the dressing room no-one could say anything, there was sadness, bitterness and disappointment because we knew we'd given an awful image."
