Benitez must go after this season. He's had six years it hasn't worked end of. Sure he's been treated badly by the Americans but he's wasted too much money and the tactics have been mistaken too often. It's time for a change and it has to be now. If he doesn't go now he'll be gone halfway into next season or before.
If he stays, will we be persisting with the Lucas/Masherano axis by any chance? maybe we just need to try it a few more times just to establish once and for all whether it's a good idea or not.
I don't think Benitez will go at the moment but I don't think he'll be in charge next season or not for very long if he does. I can see this being dragged out and dragged out. The question is not if Benitez leaves but when.
