Sheffield United have offered George Long a new deal to ward off interest from West Bromwich Albion and Middlesbrough, HITC Sport understands from sources close to the club.
Long, who has come through the ranks at Sheffield United, is out of contract this summer and he could leave as a free agent.
The news of Long's possible availability has alerted a number of clubs with West Brom and newly-promoted Middlesbrough both admirers of the 22-year-old shot-stopper.
West Brom and Middlesbrough are in the market for goalkeeping reinforcements this summer and Long figures on their wanted lists.
However, Sheffield United are determined to keep their academy product at the club and have offered Long a new four-year deal to secure his future at Bramall Lane.
Long made his debut for Sheffield United as a 17-year-old in 2011 against Swansea and he has gone on to make over a 100 appearances for the Blades.
After successful loan spells at Oxford United and Motherwell in the last two years, Long established himself as No.1 keeper this season under manager Nigel Adkins.
Long made 38 appearances in all competitions for Sheffield United this season, keeping ten clean sheets for the club.
Long is highly-regarded at Sheffield United and they see him as playing a key role in their long-term future as they look to mount a bid for promotion from League One next season.
