Do agree with that, problem with that set up though is it lacks width and defensively a bit fragile so big teams could get some joy from it.
It was never really used against Madrid or a CL big hitter though to find out i suppose, also with Neymar now its a bit difficult to use the same set up.
I much prefer a proper forward as our LW, that's why I liked that we bought Neymar (as a player type, before you go "no shit" with me ). With so many midfielder types we lacked bite against teams that defended deep (which is the majority of teams that play against us nowadays).
