Spot on. Benitez should have all the Mitrovic money, but this summer he will only have another £5 million from that sale to spend and it will be same if we sell Hayden and Shelvey in the summer. Selling players is kind of pointless for the club when it adds next to nothing to the managers budget.
But surely if it's added every year it will make a difference. Money from Sissoko, Wijnaldum, Mitrovic, Thauvin etc, money from those players if they are being paid for over 4 or 5 years would still be going into the transfer pot for this season. Cisse and Townsend too. It could work if done properly but as we all know, we don't do anything properly. After the first year, that's the last we hear of it.
