An idea shamelessly adapted from an issue of L’Equipe I was looking at over lunch today, here’s a table showing the fate of Serie A teams who were in the relegation zone after 27 games (as is current for all but Parma and their intended opponents) from 2006 to today along with their final league positions and points above the relegation zone.
The first year is a bit off, as its the year Juventus were relegated, but the rest makes interesting, if not definitive reading. Less and less often, at this stage, are teams making a break for survival, so credit to Sassuolo last season. It was about now they re-hired Eusebio Di Francesco, as I recall. You should be able to view the image full size.
