The Reds reportedly want to take Lovren and teammate Adam Lallana to Anfield in a £20m-plus switch.
When asked about Liverpool's reported interest, Lovren told Sportske Novosti: "I also heard something about that.
"I follow the media and I saw that Liverpool is allegedly interested in me. But that is all that I know so far.
"I feel great at Southampton and my contract is valid for the next three years. So the only thing I can say right now is that the club is the one who decides."
The Croatia international joined Southampton from Lyon last summer.
