and that is the even scarier thing to see with 3-5-2 vs modern winger oriented top teams... you only have 1 man/wings, your opponents can easily exploit that on counters... and that is precisely why 3-5-2 is used with high backline, because side CBs have to cover for counters, and yet with slow CBs we have as we all have seen, we are very prone to counters... can any you imagine how easy to break juve's 3-5-2 in europe? overload the midfield and then overload the wings or simply counter from wings with speedy players.
we are now so used to see matches in shit serie a and complete absent from the highest level on europe, CL is too different than that.
IMHO our 4-3-3, at least in theory should serve us better in europe, heck it may even better to sacrifice pirlo and play with marchisio-asamoah-vidal in the middle to break opponents midfield and play counters on europe, that way at very least a forward line consisted of gio-vuci-isla can be very useful with their speed.
