Over a fairly large sample, the conclusion is that we have played terrible football, among the league's most boring teams to watch. It is true that there are a couple of extreme outliers in this sample, but that does not change the main impression. During Ancelotti's period we have not seen any clear direction, apart from the only constant, a poor interpretation of catenaccio.
Many here on the forum have warned that in the long run, this approach will lead to declining points. Something it has done. But that's not the most disappointing thing. The most disappointing thing is that we have not developed as a football team. Now I hope Ancelotti will improve this for next season, because this season seems finished. Considering all the injuries, and the bad form we are in.
