Combination of things, losing the like of Ricardo, JJ and Fofana to injures when in prime from resulting spend money on replacement we didn’t need. Both JJ and Ricardo were on fire, and could have been sold for big money.
Spending big fee and wages on players that didn't improve us, Soumare, Daka, Vestergaard, Perez, Praet etc.
Losing players on frees, Tielemans, Soyuncu, Perez, Praet who cost near on 100m
Move away from the one big sale a year model.
