McAllister has no intention to leave. He's staying in Liverpool much longer. Even if Real is willing to spend like more than 100m for him, i'm sure they will not get him as Liverpool will be so reluctant to sell him. He's the tempo setter of Liverpool. It's crazy to sell him.
That's what you think, I read that Real Madrid is preparing around €120 millon for his services. Liverpool will cash in on him in other to raise funds for the purchase of Isak because they took are eyeing that striker to strengthen their attack. It's business once the price is right there's a big possibility that the deal will pull through unless maybe Real Madrid does not really want to buy.
Liverpool is already placing a bid for Isaak even without selling MacAllister. Don't be delusional. Isaak is also in the transfer stance "NOT FOR SALE" by Newcastle. Importantly, they still have some players to be sold such as Nunez and Diaz if they need money.
PL club is not as poor as you think.
