One thing Benitez can say about his Napoli side is that they pull themselves back from losing positions. I think they've recaptured 17 points this season after initially going behind.
Higuain has had such a good season with 29 goals, but he's missed penalties and missed a sitter yesterday. Napoli's failings have come via their defence. You can't concede 54 goals and expect a CL finish. You can blame the sporting director and Rafa for that, because they failed to replace Reina adequately and Koulibaly has been a terrible buy.
