We didn't spend 72 mil + 10 million bonuses on Arthur, we spent something like 17 million assuming all bonuses are activated. Barca bought Pjanic for 60 million + 5 million in bonuses from us and only then did we buy Arthur for 72 million + 10 in bonuses. It was an accounting trick, given we amortise the cost of the transfer through the duration of the contract, while the bank gives us the full amount in one lump sum from the sale.
