At the talk in at the beginning of the calendar year, shortly before his departure, Mike Coulson, confirmed the club still expected to receive something from any sale despite some shenanigans going on with lawyers during the sale from Bennett to Varghese, if that was true then, I can't see a reason as to why it would have changed.
That said, there was reporting in the summer of a release clause of £2.5million and no-one stumped that up then, he's apparently in the final year of his current deal, it's difficult to see any League One clubs paying that and as he's untested at Championship level I'd imagine clubs there might want to wait to see if he's on a free at the end of the season.
Aye that a completely nonsense, comical report. He has a £2.5 mill release clause so no club needs to pay a penny more than that. Nobody will pay anywhere near the release clause either because he can go for free in the summer. Maddison will either go in January for 1 million or so or go for a free in the summer.
