He definitely should have saved the first goal and he has let in a couple of softer looking goals so far this season. But you also have to acknowledge that he made two top drawer saves, one from Phillips and the other with the guy going through one on one.
I think his standard has probably slipped just a little bit and this happens to most keepers. I think people hold keepers to too much of a high standard. Courtois, Ederson, Allison, Donnarumma all concede their share of soft goals over the course of a season.
