Does the 'advanced stats' include injury records? Because that is pretty much the difference this season.
Games missed:
James - 17
Chilwell - most of the season
Christensen - 9
Kante - 12
Kovacic - 11
Pulisic - 14
Lukaku - 9
Werner - 10
Under any normal injury season we would have given City a serious run.
These are just the notable ones and many of them had multiple issues, played with injuries on occasion, and were forced to come back earlier than expected. It was a 6/7 week period that destroyed our season. Before that period we were a few points clear at the top and playing some good football.
