It seems to me that Isaac remains the main option and the other options are just a way to show that Liverpool are not limited in their choice (a way to strengthen their negotiating position). In general, Liverpool is behaving very strangely (after so many years of relative modesty) on the transfer market - they have already broken the transfer record by buying Wirtz and now want to break it by buying Isaac. It turns out that in one transfer window Liverpool will spend more than 250 million euros.
Ma friend, Isaak is always becoming Liverpool's main target, but his club is making clear that Isaak is in stance not for sale. I know Liverpool willing to break a new record with Isaak's transfer, but since his club is not even need money. This sounds impossible to sign him even if he already reached verbal agreement with Liverpool.
Isaak's future is fully on his club's hand. Liverpool has no chance to sign him, and they're moving to Ekitike as secondary option. I don't think they act strangely in this transfer. However, i also prefer to see them sign Isaak instead of Ekitike.
