Reds boss Rafa Benitez has been keeping a close eye on the 23-year-old over the past couple of seasons, as he seeks to increase his wide options over the summer.
The former Arsenal man has been heavily tipped to move to Anfield in recent months, having become increasingly unsettled following Blackburn’s failure to qualify for Europe.
Rovers boss Mark Hughes has rebuffed all interest so far and is desperate to hang onto Bentley, whose link-up with Paraguayan striker Roque Santa Cruz provided most of the club’s highlights this season.
But Benitez has swooped with a ₤12 million offer in an attempt to prise the England international away from Ewood Park, although Rovers reportedly will not consider anything under ₤15 million.
Bentley could replace fellow ex-Gunner Jermaine Pennant, who may leave Merseyside after just two seasons.
The former Birmingham City winger was offered to Aston Villa as part of Liverpool’s bid for Gareth Barry, while Newcastle have shown interest in the 25-year-old.
