It's very interesting to see Isaak has declared his interest to play for Liverpool. I think he will fit to the club, and it's good for Liverpool to sell Nunez, then add more money to sign him from Newcastle.
It will better if he can forces his club to decrease his release clause, then he can move to the Liverpool asap.
Liverpool combined with him is gonna be a great combination. I hope that is gonna happen soon.
If Liverpool really is serious about signing Alexander Isak then it would be best for them to offload Nunez first because I don't think Nunez has much to contribute, even though he was signed for a very expensive fee. So if Liverpool can sell him, Liverpool can at least minimize their losses and can use the funds to bring in Alexander Isak.
Alexander Isak has had a good run at Newcastle, so it stands to reason why Liverpool is interested in him and it looks like Isak is keen on Liverpool too. Now we just have to wait and see whether all of this will come true, and if Newcastle set a reasonable price for Alexander Isak, then the transfer looks likely to happen.
I have heard Al Nassr is ready in sending lucrative offer to the Liverpool in getting Nunez. This sounds good considering they most likely selling him in the summer window. They can convince Nunez to go to the Al Nassr, then they can sign Isaak.
I believe Nassr will also give him amazing price for Nunez. That's their only chance in signing Isaak from Newcastle. They need a lot of money, and selling Nunez to the saudi club is the answer.
