This is according to the Daily Mail, so it should be taken with a pinch of salt as is the case with most Liverpool transfer news. But the link to Douglas raises interesting questions.
A powerful and uncompromising centre-back, Douglas has always had potential, but the promise he holds has been overshadowed by a series of error-strewn performances and self-destructive tendencies in the past year.
Fans and pundits led clamours last season for the once highly rated defender to earn a call-up to the national team when he would earn his Dutch passport after spending six years in the country.
The Brazilian-born defender has since declared for Holland, in recognition that he was unlikely to be called up for the Seleção while based at FC Twente.
The decision was welcomed at the time by then-Holland boss Bert van Marwijk but relations with the national team have since cooled after Louis van Gaal took over the reins.
Since then, his place as the country's most promising defender has been taken up by the likes of Feyenoord duo Stefan de Vrij and Bruno Martins Indi, who have won caps in recent months. Douglas has yet to earn a cap, and the opportunities are passing him by.
At 25 years of age, he can no longer be considered as just a promising young player.
It speaks volumes that FC Twente are prepared to let the defender go this summer without a fight, although a disagreement stemming from last summer's transfer collapse may have something to do with that.
And not only is Douglas failing to live up to his potential, he also has a history.
Perhaps his most infamous moment came in 2011 during a match between FC Twente and AZ Alkmaar, as he pushed referee Ruud Bossen after receiving a red card for striking out at AZ midfielder Pontus Wernbloom.
He even lashed out at Wernbloom once more, before being dragged away by his teammates in the ensuing chaos. Holland's football governing body, the KNVB, proceeded to hand him a six-match ban for his actions.
It's no wonder the the defender could be considered damaged goods, although that didn't deter Newcastle's much-lauded scouting department last summer.
However, it may be the fact that Douglas is seemingly consigned to the bin of unfulfilled potential that attracts Brendan Rodgers.
The Liverpool boss is facing a defensive overhaul this summer, with club legend Jamie Carragher retiring and Slovakian defender Martin Skrtel reportedly heading for the exit.
Uruguayan youngster Sebastian Coates could also be sold, which would leave the team with just one recognised centre-back in Daniel Agger.
In the worst-case scenario, Rodgers could be faced with the prospect of having to replace three centre-backs in time for next season—no easy task for the manager.
Therefore, the Northern Irishman may fancy his chances at reviving Douglas' fortunes and encourage the Brazilian to find his form once more, whilst saving money for signing more reputable defenders.
If Douglas finds his form once more, Liverpool could yet have a fantastic defender on their hands for a relative pittance, should they decide to take on the gamble.
