Some pleasing things - we're looking a fair bit more solid at the back, at the moment only Brighton have conceded fewer than us. The overhaul in central defence and central midfield is pleasing. The signing of Maupay has given us a genuine alternative up front to just being stuck with Rondon in the event of an injury etc. Patterson has given us a new attacking threat on that flank. They're trying to progress the style of play - that's clear, but it'll be a slow process.
Some notes of caution - although our defensive record is good, it's probably fair to say that's been helped by Pickford being in outstanding form and a reasonable slice of luck for a change - We've had shots bounce off our woodwork 3 times in the last 2 games alone. To put numbers on that, we are overperforming our xGA by almost 5 goals, that's more than double anyone else in the league and it's reasonable to assume that won't last forever. Also, even to the naked eye, we lack much goal scoring threat. DCL's return should hopefully help, but you're going to have to hope that goals come from elsewhere in the team and it's hard to see where that might be exactly - Maupay might just about get double figures if he plays enough (although those minutes would likely be mostly at the expense of DCL), Gordon and Gray might chip in with a few, although it's difficult to see either getting double figures. McNeil has never been particularly prolific, so it's tough to rely on any output from him, Iwobi is a man reborn, but that doesn't really extend to much of a goal scoring threat, and then you have whoever his partner in midfield is, likely Onana, so we'll have to hope he has a few goals in him (and there's not enough evidence either way to hazard a guess on that yet)
What I've seen has generally been an improvement on last season so far and, even though West Ham wasn't a great performance, the win is nice to ease any early pressure, but I'm reluctant to get too carried away just yet. The underlying numbers (admittedly not for everyone) aren't much to shout about yet, although I think we'd all agree that the commitment and general performances seem much better.
