The 22-year-old has impressed for the Bluebirds in the Premier League, but he is expected to leave the club following their relegation.
According to The Mirror, Brendan Rodgers attempted to sign him last summer from Tottenham Hotspur, but the Londoners refused to sell him to a rival club.
It is believed that Caulker has a relegation release clause, which Liverpool will be hoping to exploit.
