Well then whatever source you are looking at is wrong I’m afraid
prior to the window before the Coutinho windfall, they signed mane, Wijnaldum, Salah, Robertson and Alex olade chamberlin, they alone cost more than the figure you have quoted above.
Either way to suggest another poster is making things up when you have no clarity in your argument yourself is a trifle cheeky
Salah, robertson and oxlade chamberlin were bought in the summer of 2017. Klopp joined liverpool in 2015.
Come back in 2 years time.
Even17/18 they made profit on transfers (yes helped by the sale of coutinho).

Where this £150m above sales comes from, i don't know.
