The thing with Robben and Duff is that they're both out and out wingers, although Hazard and Willian can play on the wing, it's best when they can interchange and not be forced to stay out on the wing. I would compare Duff and Robben to the likes of Moses and Schurrle in terms of how direct they are. Back then we were playing counter attack football, similar to United, look at how many wingers they have, Young, Valancia, Nani and Zaha. We're going to play a different style under Mourinho now considering the amount of attacking Midfielders we have, it's not about counter attacking at blistering pace, more like controlling the pace and tempo of the game.
