Yep, Benitez loves the 4-2-3-1!
Only difference will be a faster movement of the ball, defending & movement in units - so well organised,
He prefers 2 holding midfielders rather than one holding & the other being box-to-box.
As for Torres, not sure how he'll facilitate him with Oscar, Hazard & Mata. At Liverpool, Gerard or Xabi Alonso used to give him the 'through pass' where the majority of his goals came from. Oscar, Hazard & Mata hold onto the ball more & prefer the give-and-go ultimatley.
