The Egyptian forward is now on 43 goals for the season after netting twice in the 5-2 win over former club Roma in the Champions League this week.
Salah is seen as a strong contender for the Ballon d'Or award, which has been dominated by Cristiano Ronaldo and Lionel Messi for the past decade, and Lovren has no doubt that the 25-year-old warrants being held in such high regard.
"He is the one. He is becoming a superstar. It looks easy what he does but it is very difficult," he told reporters after Salah's latest impressive display, which also included a couple of assists.
"If he continues like that - I don't know if this is the right time to put pressure on him - but I believe he should be regarded as one of the best three in the world at the end of the year.
"He deserves to be mentioned for the Ballon d'Or - when people talk about Messi and Ronaldo they should also talk about Salah. He deserves the credit but I think he deserves even more to be honest."
Salah requires just four more goals to equal Ian Rush's long-standing record of 47 in a single season.
