He asked his team to explore the way he can move to Liverpool, but it most likely his club prevent it. He's still under long term contract with Newcastle, which is still three years away.
Well, we can interpret Isak statement in different ways but he didn't specifically mention that he wants a transfer. He wants to explore is quite different from he wants a transfer because he still has up to three years contract with Newcastle. He may be talking about his salary increment indirectly but who knows? However, if Liverpool is able to push through the deal and make it a successful one, it's definitely going to be one of the best transfer market for them. I also read that Manchester united is interested in him but I doubt it. We are really going to witness impressive games next season with the signings in the big six clubs already.
