£400+ invested in 18 months, a superb tactical coach, terrible dressing room management, started well with limited squad depth in his first season, led them back to the champions, and had injury crises in his second season. ETH stays.

Arteta spent around £700m  to get the team where they are now, Klopp and Pep all started badly and got backed so sacking him now makes no sense with the huge injury list he had to deal with.
