The interesting thing is that there is still a possibility for Liverpool to sign Alexander Isak as well!

But it depends on whether they sell Luis Díaz this summer. Bayern Munich is after him recently you know. So far they haven't made a satisfying offer for Liverpool yet.
Can you imagine Liverpool getting Isak too after Ekitiké signing? Arne Slot really wants to dominate everywhere...
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.
Liverpool is becoming a threat to other teams in EPL they have a complete team already and the presence of Ekitike is another big team in the team that makes them completely strong but seeing Isak news as a targeted player yet again from Liverpool shows that they are planning to dominate the league like Manchester City did in the past. Slot knows how he plans to pair the two players to ensure that the presence of one doesn't affect the other player but I don't think Newcastle United will be willing to release the player unless they want to make money selling him very expensive for Liverpool.
