Is di Maria really so much better than Sanchez? As in to the tune of £35m? Actually, Sanchez is almost certainly a better player, so either Arsenal got the bargain of the century or utd are about to pay massively, hugely, gargantuan-ly over the odds. Record breaking overpayment?
It's hard to know these days as deals like Luiz for 50M make it harder and harder to pin down a players true value. It does seem to be a case of whatever the buying club is willing to pay.
Di Maria is definitely overpriced at 70m (if that's what he's going for) but then you look at deals like Hulk to Zenit and think, well it could be worse.
