On an unforgettable night at Anfield, the Reds overturned a 3-0 first leg deficit to reach the final of the competition at the expense of the Catalan club.
Pique, who was at the heart of the Barca defence that night has revealed the anger he felt caused him to ‘throw things’ in the changing room afterwards.
Asked during an interview with Spanish TV3 program Nexes about the most significant defeat of his career, he answered: “Anfield.”
He added: “I’m not the kind of player who comes into the dressing room throwing things on the floor to express my anger, but because of the first-leg advantage, I did just that.”
Luis Suarez and a brace from Lionel Messi at the Nou Camp had given Barcelona a commanding first leg lead in the semi-final, with Pique and his teammates perhaps already thinking that they had one foot in the final.
However, two goals each from Divok Origi and Gerogino Wijnaldum turned the tie on its head and sent Barca crashing out in humiliating circumstances.
Despite winning the Champions League three times with Barca, Pique has also been a part of repeated humiliations with the club.
A year before the Liverpool defeat, they allowed Roma to overturn a 4-1 first leg scoreline to progress on away goals.
Last year, they suffered a devastating 8-2 defeat to eventual winners Bayern Munich and this year lost 4-1 to Paris Saint Germain at home in the first leg of their 5-2 aggregate last 16 exit.
Behind the scenes turmoil saw president Josep Maria Bartomeu resign earlier this season and elections leading to the return of Joan Laporta in the role.
Pique, 34, hinted at a future run for office at the club himself following his eventual retirement.
‘In these elections, I saw myself reflected,” he added. “I have a lot of information from Barca and I wanted to see how they did it.
“It was a worthy fight. And I hope that Laporta fulfills the mandate. But I do not know, I do not know if in the future I will be president. I feel that I am still a footballer.”
