There's nothing to catch up with, really. According to xG, we have both scored and conceded about as many goals as we should have, and we also have as many points as we statistically deserve midway through the season.
It would have been a worrying trend (shades of LvG), had we been 2-3 seasons into ETH's tenure. Given the state of the squad he inherited, that fact that he's also new to the league, and that United - as an organization - still seems to be operating under the assumption that the manager should be able to have an answer to every problem, ETH is doing well. Players are improving, team spirit seems high, and the team shape and movement is obviously better.
The stats indicate that we're doing well defensively. Fifteen of the twenty goals we have let in came in the 4 defeats (Brentford, Brighton, City, AV) we have suffered. Five goals in the other eleven games is as good as it gets. It can be a sign, though, that when we are forced to take some risks, for whatever reason, with our positioning, we are still vulnerable.
Offensively, there's still work to be done. Going back to Solskjaer's days, United didn't have a problem converting low probability chances. The quality to finish is there. But, as DSG argued, we do have a problem creating high probability ones. What we lack are the "easy" goals, if you like. So, yes, our xG ratio leaves a lot to be desired regarding our game in the final third. The "eye test" can make you feel as good and optimistic as you'd like, but United have scored 13 (not counter-attacking) goals in 15 matches from open play and just one from set-pieces. That's not subjective, it's a fact. And it's midtable quality. Newcastle have 21 goals from open play and Spurs have already scored 10 from dead-ball situations.
But, as mentioned, it's still early days. We are a work in progress and there's a lot of room for improvement. You can tell that we're still trying to strike the right balance between treating the ball well in possession and getting the best out of a frontline that is more suited to a direct game.
But it begs the question, since Gakpo chose the scousers over us, what kind of forward do we need? The majority on here are arguing in favour of an out and out forward. The stats indicate that conversation isn't our main issue. Some will point towards Haaland, but City have the engine to support any player. What about Newcastle, Arsenal and Liverpool then? Let's see who we'll get next summer.
