we didn't play bad.
that was our standard performance, that's what's you see in a match when one team park the bus, barca-chelsea comes to mind.
we lost because of individual errors (buffon and peluso) and conte underestimated the opponent or rather overestimate his former player (peluso)
about our repeating failures to convert chances, it has became the trait of this team I'm afraid, how else can you explain that. matri denied a clear penalty, vucinic hit the bar and missed an open goal from 1.5 meters... especially those vucinic misses, it happened just because the lack of luck, he was in the good positions, did good efforts but yet the ball just didn't get in.
