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.
The money that Liverpool will use to buy Isak from Newcastle United isn't a problem, and that will not push Liverpool to sell Mac Allister to Real Madrid if Liverpool doesn't want Mac Allister to leave Anfield this season. Liverpool has already submitted a €120 million bid for Isak, and they are waiting for Newcastle United's response to know if Newcastle United has changed their mind about selling Isak this season.
