Liverpool produced arguably one of the greatest comebacks in Europa League history after claiming a 4-3 victory over Dortmund in the quarter-finals of the competition earlier this month.
Lovren was the man who grabbed the winner late into injury time and the defender has gone on to reveal that scoring the goal has been the best moment of his career.
The Croatian international told the Sunday Times: "You know, when the ball was in the air and I was there, I thought 'this is the time'. I said to myself; 'it's now or never.
"I don't know… it was a relief I would say. A relief in me. Difficult to describe. Emotions. Angry. Relief. Powerful in the moment... All of those things together.
"It was everything that had happened over the last couple of months, also the last couple of years. Always the light on me. You know, to do something special… so I can say, maybe, 'I'm sorry,' for the beginning. So maybe the people will now say okay, we accept that.
"That moment you connect, every player needs it. I was so proud and angry; I felt I was saying, 'yeah, that's me, that's the Dejan you know, who is the fighter until the end, who will never say that it's over.'
"This is a good beginning for me, a connection with the fans and the people. One of the best days of my life was moving to Liverpool but the goal is the best moment of my career, to be honest."
