If Real Madrid are prepared to pay over £100m for Bruno, we take it. I'm sorry, love the bloke, but in the evolution it would make sense. Why? Because that £100m, however it's paid, is recognised instantly under FFP, whereas incomings are valued via amortisation. It means we can purchase 5 PL ready players instantly without touching FFP, each of them could be worth £100m and instead of us spending £500m, under FFP we've sold for £100m and paid (assuming each player signs a five year deal) £100m, which still leaves daylight under FFP and more to spend if needs be.
Of course, we won't be spending £500m on players, but it's then conceivable we could spend around £200m in the Summer across 8+ positions, significantly strengthening the squad. This is the nature of the beast for me, clubs must sell to progress and nobody is 'above' it - except for Real, Man U (replacing Barca) and Bayern. Liverpool sold Coutinho, City sold Cancelo, Chelsea will start losing players this Summer (they have to), Barca need to raise £170m.
It's worth noting that under FFP we've actually spent around £70m in total since the new ownership.
