Coutinho money ;)
There's this myth that Liverpool don't spend big money, but they spent £40m on Gapko in January, £85m on Nunez last summer, Luiz for £50m the January before.
As you say, they have the money, it's whether they want to make a single statement signing and just sign Bellingham, and hope to get away with not fixing other positions for another 12 months.
It's a risk, but might be okay with that to keep Klopp happy. It's really only the midfield they need to replenish with Fabinho, Henderson and Milner on their last legs.
