Yes, Matri's.
We didn't win the Scudetto that year because we couldn't beat a single team who were remotely good at defending. Perhaps we would've, if important players like KPB, Aqua, TS and MVB weren't injured/unavailable all the time and we didn't have false midfielders(Noce) starting every game. Instead we were a predictable Ibra+10 side who would be easily shut down and beaten on the counters and set pieces by any above average side who were willing to park the bus(Arsenal and Enrique's Roma are among the few who weren't).
That gol di Muntari Juve game was an anomaly, since Ibra was suspended, but I'm not sure we would've won even if we had gone 2 goals up. We started out strongly, but quickly tired out and Juve took over the game completely when Conte switched to 4-3-3. We don't know how the game would've ended if the Muntari goal was allowed. I don't think it was decisive since we kept losing big games and Ibra always has a post-CL elimination depression where he drags the whole team down with him(but he was also the reason we were in the title race for so long).
Can't blame Allegri though(except maybe for the injuries). A flat-track bully side was the best we could wish for, with all those injuries. He got the big game results in 10/11 season and with Juve. It's a whole lot easier when there's some continuity and quality in more than just one part of the team.
