Bentley, 22, was on the books at Arsenal before being released in 2008, and the Basildon-born stopper joined nearby Southend United shortly after.
The giant 6ft 4in stopper has come up through the ranks at Roots Hall, and since making his first-team debut in 2011, he's racked up more than 150 appearances for the Shrimpers.
However, Bentley is out of contract this summer, and looks set to leave Southend having so far snubbed any chance of a contract extension - and reports suggest it's a four-team race for his signature.
The Southend Echo report that Rangers remain keen to lure Bentley up to Ibrox this summer, but three English clubs are also keen; Premier League sides Bournemouth and Burnley, as well as Championship side Brentford.
The Gers saw Wes Foderingham impress in his first season at Ibrox, but with Cammy Bell seemingly having little future at Rangers and January signing Maciej Gostomski already gone, manager Mark Warburton may look to bring in another shot stopper this summer.
Warburton has already landed three players from English clubs as Accrington duo Matt Crooks and Josh Windass, as well as Liverpool teenager Jordan Rosster, have signed in controversial fashion, as they have penned pre-contract agreement for minimal compensation.
The compensation laws for out of contract players means that Scottish clubs can sign players from England for a fraction of the cost that an English club would have to pay.
That would be the case for Bentley to, as he's out of contract this summer, and could join Rangers for a fee far below what Southend would demand in a tribunal - and having done so already this summer, that could be an appealing avenue for Warburton and Rangers, even if they face a battle with Premier League clubs for his signature.
