mdgoonah41 which players havent they been able to shift recently? they sold a worthless player to arsenal for £65m this summer. they've sold a bunch of other guys with very low profiles for balogun fees.
They've also got mountains of deadwood that they had to write off huge amounts on. They spent €115m on Lukaku and can't get a buyer for him, lost €44m on Pulisic, €15m on Koulibaly, €12m on Aubayemang, Bakayoko 40m, Rahman 26, Ziyech...
Amortisation isn't an infinite money cheat. 1bn stretched over 8 year contracts is still a 125m a year that they need to cover. That'd be somewhere between 22-25% of their revenue, which at least this season is going to fall significantly. It doesn't sound like they're being prudent with their wage bill either so selling players is probably going to be needed every season for them to comply, and probably a lot of them.
