Glasgow Rangers boss Mark Warburton has been linked with potentially trying to bring the goalkeeper to Ibrox.
The Evening Times claims that the Light Blues are interested in signing the goalkeeper during the window, as Mark Warburton looks to bolster his ranks ahead of the club's return to the Scottish Premiership.
And if he is keen on making a move for the stopper, his interest is likely to have increased based on Brown's assessment of Bentley's situation.
"I expect him to leave if I'm honest and make a career move to a higher level but we ideally need to know soon what he's decided to do," he told the Evening Times.
The 22-year-old has been a key man for the Shrimpers over the past few seasons. His form was instrumental in guiding the side into League One ahead of this past season, before he helped the team secure a safe mid-table finish in the third tier this year.
Should the Gers make a move in the coming weeks, it is difficult to know exactly what role Bentley will play at Ibrox. Wes Foderingham has done a good job in his first season with the side, helping them secure promotion from the Scottish Championship, while Cammy Bell is surely one of the best back-up options in Scotland.
However, with The Scottish Sun claiming previously that the latter is being chased by three clubs, it is possible that Bentley's arrival would see Warburton let Bell move on, leaving the remaining two to battle it out for the number one spot.
