Speaking to BeIN SPORTS, he said: "I heard people saying I had a hard season but I don't agree with that".
Lovren's comments raised eyebrows last week, but his manager at Liverpool supports the Croatian.
The defender, who also reached the Champions League final with Liverpool in May, will face France in the World Cup final on Sunday and the 29-year-old feels he has proved himself this season.
Lovren also called for his national team captain Luka Modric to be crowned the 2018 Ballon d'Or victor after leading the country to their first ever World Cup final.
"People don't think about that, but if you go into detail it's not a big surprise that Croatia are where they are". Croatia do not have a world class right-back and left-back, but they do not concede. They are offensive in the midfield with [Ivan] Rakitic, [Marcelo] Brozovic, [Luka] Modric, so somebody needs to fix all that.

Moscow's Luzhniki Stadium is the venue for today's World Cup final, with Lovren's Croatia to take on France.
Two years ago, Croatia's campaign at the 2016 European Championship was overshadowed by turmoil in the stands as fans hurled dozens of flares onto the field in protest against the football federation leadership. Okay, we did not win that but that means only 11 players were better than us, and only two centre-halves.
ILovren also provided an opinion that a lot more people can get onboard with, saying that teammate Luka Modric deserves to win the Ballon d'Or if Croatia beat France on Sunday.
Asked what the difference between the two sides was, Lovren replied: "Mentally".
"Now we can all be happy for him [Lovren] and we are happy that Jordan maybe and Trent will be coming [back to Liverpool] earlier".
The defender then wrote: "I don't mind when people talk s*** about me, it says more about them!" A year before that, a swastika was drawn on the field before a national-team game.
