The bank is putting pressure on Blackburn Rovers.
Venky's, the under-fire owners who acquired Rovers from the Jack Walker trust in a £23million deal 12 months ago, have failed to pay off any of the £21m debt they inherited.
The Daily Telegraph reports Blackburn's centralised television income for this season and parachute payments, should they be relegated, has been provided as security to satisfy Barclays.
Blackburn will be given £30m this year through broadcast revenue, and are set to receive a minimum of £48m over four years if they're demoted to the Championship.
With pressure mounting from Barclays, Venky's are unlikely to plough any money into the club when the window re-opens next month.
