Andrews was his assistant, so he's basically carrying the same momentum and methods that Frank helped to produce over a number of years there. It's not like he was a random person with a different system proving A/B tests. Neither should a person expect anything to particularly crumble in the immediate stage. If Keith (or Brenford) fucks anything up, it'll be beyond January at the earliest.
Generally, the main change so far is that Thiago has stepped in for Wissa and is about par for his output. Shade is about par to match his output from last season. They are still missing a 20-goal winger in their output (Ouattara quite far off replacing Mbuembo, and Reiss Nelson hasn't really featured)
So far, I'd say he has got a decent return out of Richarlison, but Kolo Muani is basically a one-season wonder that PSG don't want because he is a bit shit (let's be honest). Xavi Simons was sold by Barcelona, and since PSG twice - so is still quite far from a player anyone should "expect" to be getting a decent return from. Similarly, at this stage, Tel is little more than a 'potential' signing who has done absolutely nothing (bit of a Bayern reject and not a £30m player; we all seem to agree). I like Odobert, as he's a "bums off seats" player who I think is by far the best LW in the squad, but it isn't saying much
I just don't understand the logic in expecting more from this group than they've ever done before in their career. I'm pretty sure, for example, that this is Richarlisons most proflic seasons so far, with 7 PL goals in 18 games (0.39 goals per game). The most he's ever had is 13 from 35 (0.37 goals per game) at Everton. Kudus is putting the kind of numbers you'd expect from him.
If Son was still here with 2 or 3 goals, then there might be a point to be made, but with Maddison, Solanke, and Kulusevski fully fit, I wouldn't seriously see Muani, Johnson or Tel getting anything but token sub minutes. Kudus would probably be rotated a lot more too.
