How did we play 4-3-1-2 last year?
It was indicative that he (Conte) played 4-3-3 vs Real since he realized he made a mistake before. Too bad he didn't stick with that system in our other European games.
He is talking about the Bayern game not the season after.
1) There were no signs that "it didn't work in Europe" since it did not stop us from defeating Shakhtar, thrashing Chelsea and thrashing Celtic. It was working pretty well in fact we were undefeated all the way to Bayern and put in great displays along the way.
2) We played 4-3-1-2 last season because we had 4 world class CMs and an AM (pereyra). But back then it was Pogba's first season and we had no AM at all. He was still just a sub for marchisio if you recall. Plus, Vidal was injured for our home leg so there goes your 4-3-1-2 and we did not have evra to play leftback.
Also, the attack was matri and quags if you have forgotten. No Tevez no Llorente. So very different squads. Pirlo and Vidal were the stand out stars in the squad and so it wouldnt have been very smart to push both of them out of their best positions.
3) The madrid game had marchisio as a defensive winger to neutralize their unstoppable wingers and it didnt work. It certainly was not a possible permanent formation.
4) This was his first ever CL experience for God's sake and the same applies for our entire squad with one or two exceptions.
5) We weren't even humiliated by Bayern. Their superiority was evident but we did not bend over at all. Their goals were largely flukes. Compared to how the experienced teams that face them fared we did well.
Hindsight is easy.
