Liverpool has't stopped yet. They're trying to hunt more talent to be recruited. They have done with Frimpong, Wirtz (medical check up), Kerkez, (still in the negotiation), and add Isaak as their last target. Their target to sign Isaak from Newcastle is just getting even more possible with Nunez who is still in the process to go to the Napoli(i expect him to play for that italian club).
I think we will see Isaak to wear Liverpool's jersey as he has open the move to the any big club that play in UCL.
I'm beginning to be scared of Liverpool truly. As a Manchester fan I will do all I came to ensure that Liverpool fail to get whoever they to. They get the signature of Alexander Isak from Newcastle United and I'm sure as hell he'll help Liverpool towards a successfull league tittle again. They're a good side, I don't want to see them winning the league competition Back to back, this will extend their dominace and also make the league boring.
If by chance this signing happens, I am sorry for the rest EPL clubs because Liverpool will definitely win back to back and possibly win the champions. I won't be troubled if Liverpool wins the EPL again provided that Pep will struggle again this season.
