And we have got the here we go!

Ekitiké is officially joining Liverpool. However his cost will be really huge. But on the other hand he is cheaper than Isak at least. I don't think Newcastle would let him go under his current value (120 million euros).
Ekitike probably cost Liverpool for €95m. That's a lot of money. Also you said that he's cheaper than Isaak, but i'd consider him riskier bet than Isaak. There's only 25m gap between his price and Isaak. I'd go for Isaak 120m rather than him, but sadly Newcastle would never sell him.
Some transfers require risk, and risk can lead to the trophy you desire. Liverpool took a risk considering the cost of this transfer, but if it works out the way they want, no one will remember the transfer fee. I think major clubs should make similar transfers and bring in surprise players.
Isaak is a proven player who has the potential to make a significant contribution to any team. Liverpool could have signed Isaak, but they opted for another player. I think they'll get a good result from this transfer.
