Who told you that? There was excellent summary on YouTube of how Moyes immediately improved us last season by pushing Myko further forward and having JOB as a third centre back. I don't recall us doing that when he was here last time. We have also changed tactics this season with Grealish and KDH playing. But because Moyes isn't from Austria you're convinced he must be a dour regressive manager.
I think the comment about last season is a fair one. We were energetic, pressing high, and winning the ball higher up the pitch, we had Alcaraz/Doucoure bursting through the lines and we had a compact mid block with fast transitions. So direct speed on transition was fast 1.9 m/s, turnover leading to shots on goal was 1.3 per game, average possession length 10.4 seconds.
Then we had the summer transfer window and
Moyes reverted to type, less progressive carries per 90 minutes (down 35%), slower direct speed on transitions down to 1.5 m/s, less turnovers leading to shots (down 46%) and average possession length up to 13.2 seconds.
In short we are playing slower and are less direct. Now you can argue the merits of changing tack but at the minute we aren't winning as many points as we were last season and we've spent £100m. If that continues to the end of the season then its a big failure. The second half against Palace was effectively the only time we've played like last season. It was also noticeable in that game that
Grealish in the second half reverted more to his playing type at Villa under Dean Smith.
