"From my point of view, people said I had a hard season but I don't agree with that", he told BeIN Sports after beating England.
The Liverpool centre back also said his country was now thirsty for "revenge" over France in Sunday's showpiece as they seek to banish the memory of their semi-final defeat to same nation 20 years ago.
The signing of a world class goalkeeper remains the primary target for Liverpool this summer, particularly following Loris Karius' high profile mistakes in the Champions League final at the end of May.
Zlatko Dalic's team ended England's pursuit of glory at the tournament in Russian Federation with a 2-1 victory against the Three Lions after extra-time at Luzhniki Stadium.
"But I like to challenge these strikers and to show to everyone that I'm one of the best defenders".
He said: "It feels incredible, especially after everything that was said about us before the game". We will never forget this.
Lovren was able to shackle Harry Kane for the majority of the 120 minutes, and was asked after the game how Croatia have so much talent within their ranks.
"There is too much about me but, whatever, this is what gets me more motivated to work harder and prove everyone wrong".
And he is delighted that this current Croatian generation have finally lived up to, and now surpassed, the standards of the 1998 team which reached the semi-finals.
"Now we have the chance to do something even better and hopefully we can do it".
"England are one of the favourites to win the World Cup and you have to respect that", he said. "He knows what I went through".
