I think he enjoys being at Everton, I think he wants to prove a point, not just to Everton fans but also Liverpool hierarchy. He would have known the takeover was close even a few months ago, so he could have waited it out. And whilst Newcastle isnt a million miles a way, its not as close to home as Everton. So I dont see him being interested, unless its a case of Everton arent spending for 5 years, which I dont think is the case
From a Newcastle view I think if Newcastle want to go crazy on spending - they'll try for someone else, Mourinho, Mancini, Conte - If they are going to go nuts, they'll go all out. If they arent going to go nuts, then I reckon they might try to tempt someone like Brendan Rodgers.
I dont think it suits either party, its just a convenient newspaper story
