It will be a very good signing for Liverpool if they can complete the signing of Isak, but I really don't see Liverpool pushing to sign him since they already signed Ekitike. They already have a good striker in him and I don't think Arne Slot will want to have unhappy players in the team, because that will definitely affect the team spirit . Signing of Isak will definitely affect Ekitike and that will make him unhappy if he doesn't get playing time. So my guess will be Isak staying with Newcastle,  probably renewing his contract and getting a big check.
