Realistically Gylfi isn't sellable. No-one will want to take on board that salary and he's a few years past his peak.
This is what I've been saying. Our options with him are limited.
1) sell/loan him for pennies on the dollar and surely still continue to have to pay most of his weekly wages, or
2) keep him for - fucking hell - 30 June 2022 when his contract expires, not getting a penny (pence?) for him but having all his wages come off the books.
