Asensio and Isco for Salah maybe
Coutinho is going eventually but I highly doubt its going to happen over this winter transfer season unless we get the right fit replacement which is also highly unlikely. What is significant though is that he ain't going to any of the other Top 6 EPL clubs, not even the 2 Mancs clubs.
As for Suarez leaving, let's get it straight here, no doubt the lure of Barca FC was there, but just as important was the fact that his girlfriend, and current wife, Sofía Balbi, had moved to Barcelona while he was still in South America which first lured him to Europe in the first place to be closer to her and finally ended together with her family in Barcelona itself
