Players like this are why we should sell high value players. Sell someone for £40mil + punt Gomes on a free.
You then have the 40mil fee + both players wages off the books minus the book value.
In theory a free makes sense but never that straght forward, as you were saying we will pay more in wages over his final two years then we would crystallising a loss, in those cases players usually look for a negotiated settlement to end their contract, a loan is an option - the problem would be % of his wage as there isnt likely to be a big market for him.
The stumbling block is we are legally obliged to honor his contract so hes within his rights to "fight for his place".
