I'd give him a free transfer rather than subsidise his wages. The only reason to take £15m and then give most of it back as salary over 2 years is if his new club are adhering to some kind of salary capWhich is also why we might actually find a taker this summer.
15m plus some of his wages subsidized. Could see us breaking even on the remaining 2 years. Maybe a sub but he still played almost every Serie A game for title-winning Lazio.
