Lovren snapped at one journalist who raised his first-half substitution last season at Tottenham going into the game.
Asked if he felt extra motivation to prove himself, with so many questioning his ability, Lovren said: “Yes, and I think I've done that without being arrogant.
“I think definitely, if you're in the final, you're part of the two best teams in the world.
“Before the game I received a question like 'what do you think about the 4-1?' [Liverpool's defeat away to Spurs last season].
“I really don't understand these questions, always looking back to where I made some mistakes. I really don't understand.
“There's too much about me. But whatever, this is what gets me more motivated to work harder and prove everyone wrong - everyone."
