I'm sorry but it is a close decision surely on if David Moyes or ETH is the worst of the two?
Keep in mind that Moyes got sacked with 4 games to go, so Ten Hag has played one more game:
Moyes (34 games)
* 7th place (far in front of 8th)
* 57 points
* +16 goal difference
* CL quarter finals (crushed his CL group)
* Best player (Van Persie) injured for large parts of the season
Ten Hag (35 games)
* 8th place
* 54 points
* -3 goal difference
* Worst CL campaign ever (last in group)
Ten Hag has obviously had worse luck with injuries and he can still win the FA cup, but I think the numbers speak for themselves. Moyes clearly did better in the PL and way better in Europe.
But that's only looking at this season. When looking at last season as well then it becomes much closer. But there is not much between them.
