A few things about our defense.
For the ones giving higher ratings on Chiellini than Legro, i suggest you to watch again the goals and see that in the first goal, Amauri dribbled trough the both of them and his shoot has gone just between them, so they share the fault. Buffon was out of position, he didnt expected an on target shoot from that distance and with two defenders on him, i generally give the blame to the keepers when we speak about long range shoots, because they have more time to react than usually, but that goal was out of reach, only a very good positioning would have helped.
In the second goal, Chiellini marks Amauri all by himself and he is just standing there and looking at him how he heads it in, Buffon has almost (again positioning) no blame here and the only other defender with partial blame is Grygera, but Grygera was marking his man and attempted (at least) to block that cross, the crosser didnt have the time and the space for the perfect cross and there is no way to block a team of never making any cross, even after the worst circumstances.
Thats why i said that Chiellini is responsible for 1.5 goals
(not to mention he almost scored an own goal)
and Legro for 0.5, also you may add the fact that Legro had some positive contri in the offense and you get my ratings, i cant see how anyone can rate Chiellini higher than Legro for this match. I also consider Chiellini a better player than Legro, but we rate today's performance, not the player's value, or demonstration of skills.
In the third goal, i blame Buffon, our players withdraw further away than our penalty area and Buffon had a clear straight line and visual contact with Cassani, you can see that from the camera that is placed right from the back of the shooter,
i m confident that the best keeper in the world can block much more difficult balls than that!!
