The 22-year-old became the Shrimpers’ hero last season, helping the club win the League Two playoff final with two penalty saves during an intense shootout victory over Wycombe Wanderers.
As such, he has since attracted plenty of attention over the summer and has already been the subject of a failed £1 million bid from Hull, according to the report.
Why Nottingham Forest should seek a deal:
Following Karl Darlow’s switch to Newcastle United, Forsest now only have goalkeepers Dorus de Vries and the relatively unknown Dimitar Evtimov on their books permanently.
Ben Hamer joined the club from Leicester City on loan, yet he’s fairly highly-rated among the Foxes’ support and it’s unlikely that there is any real chance of a potential future permanent deal.
The East Midlands outfit need to start building for the future, bringing in young players with potential resale value as they look to bounce back from their failed promotion bids and ensuing problems with FFP.
While they’re currently being limited to transfer activity, Forest still have a number of players deemed surplus to requirements they ought to shift on this summer.
Bentley is widely regarded as one of the best shot-stoppers outside the top flight and last season won a host of personal awards, making the PFA League Two Team of the Year too.
