Who was going to buy Mina and Gomes? Do you think teams were queuing up to take them off our hands?
The point, which you've missed, is that we don't have sellable assets other than those we've sold and we have for some years now looked like a basket case club, who change managers in the middle of transfer windows who are bordering on relegation every year.
We've had to sell Onana, Richarlison, Gordon + Simms, Cannon, Dobbin.
On Gordon specifically, he may be worth twice as much now, but the value is based on him playing for a much better team, who don't need to sell, who can showcase him across European competition (we couldn't do that).
