If the move doesn't happen then the media will paint Newcastle and their brown owners as the bad guys, denying Isak his dream move to the biggest and bestest football club to have ever existed. Isak will appropriately be painted as the victim.
The fact Isak has seemingly spat his dummy out, and if he genuinely is refusing to play (therefore breaching contract) will be brushed over.
No-one in the media will dare to call out Liverpool for their tapping up tactics, in the same way the circumstances surrounding the Van Dijk move was forgotten about.
