After acquiring Wirts for €125 million, I read that Liverpool is ready to offer even more for Newcastle's Alexander Isak. Allegedly Liverpool has made an offer of £121 million (so almost €125 million) but it was rejected by Newcastle, who claim Isak is not for sale.
Rumours are they received a much higher offer from Saudi Al-Hilal. If true, I don't think that would be a direction Isak would want to go at this stage of his career. Then again, Saudis have very deep pockets, so who knows?
