Indeed, however his success rate stats (not the be all and end all) were the worst in the Championship! There were times when he tried more impossible balls through the eye of a needle than Palmer. Commendable but not conducive to building decent attacks, especially then when possession is ceded he shows little capability to do his job defensively.
Gut feel is he’s not on huge wages. Signed a 3+1 deal in May 2019 aged 20, so I doubt he commanded silly money then.
The gamble hasn’t worked, but as you say it wasn’t a “new deal”, just a chance to see if we could eke a fee out of someone, or that he might buckle down and make it here.
Someone will take him, either permanently or on loan, and I suspect most if not all of his wages will be covered, so I suspect any loss be tinsy-winsy.
Amortisation-wise, virtually all of his fee to Luton has been “sunk”, so very different to someone like Palmer.
