But assuming a budget as is of 100m that 70m could potentially cover another 250m of amortisation and wages and I think in reality we would not spend 350m in one summer even if we had the PSR wiggle room. It would be better to preserve some PSR wiggle room for future years and finally end the dependency on annual player sales. The last thing we want is to have to sell players in future summers just to cover the amortisation / wages we already have let alone to improve the team. That's the situation we've been in.You could accomplish the same by spending all 70m on the squad this year, and then selling 30m of the squad next year.
You don't need Roma for that. It's why Villa moves players on like Diaby, Duran etc.
