Minus the fee we paid for Mkhitaryan. £27m + £55m - £17m? ~ £67m?
People don't mind players costing. The issue is players costing but hardly ever benefiting the club. It definitely shouldn't be about profit and loss. Accountants need to look at it as: a player who hardly plays, or plays little better than a youth prospect is deadwood. Their very presence at the club prevents one getting, or promoting a player with prospects.
Unfortunately many people are burdened by a sunk cost mentality: we paid £X for player Y, so now we want £X back when we "sell" him. Many cannot stand to make a loss, on a deal and would rather the goods rot or gather dust until their value is entirely depreciated. A better mentality is about building a winning team. In that case, any player blocking the way is a burden. Burdens should be off-loaded with no expectation of breaking-even. Of course, the implication of this is we'll have a thread-bare squad with a 2nd-11 of mostly U-23s.
We should've let Roma have Smalling for £13m. That's more than we paid. He's been a loyal servant so doesn't deserve to have his career hindered. It's not as if anyone offered us more.
It'd be better if we stopped paying non-core players so much. Lingard's wages are 3 or 4 times what he'd get elsewhere. Worse: if we give him a new deal he'd expect a pay rise. This hasn't been helped by bringing Dan James in on big wages (way better than he's get elsewhere - possibly double what we should be paying him). James went from £7k/week to £67k/week just because United management are easily conned into paying that. God knows who put this wage structure in place?
