I bet if you were to do those stats for everyone at Haaland’s age, the difference would be ridiculous. He’s scoring for fun at the age of 22, in what’s supposed to be the most difficult league in the world and people are calling him an average footballer
Here you go:
Numbers from club football (all comps) from top 5 league teams uptill the season before they turned 23:
Haaland (Dortmund and City):
1,15 goals/90
0,26 assists/90
1,41 goals+assists/90
Lewandowski (Dortmund):
0,41 goals/90
0,18 assists/90
0,59 goals+assists/90
Suarez didn't play in a top five league before he turned 24
Benzema (Lyon):
0,58 goals/90
0,25 assists/90
0,83 goals+assists/90
Aguero (Atletico):
0,52 goals/90
0,23 assists/90
0,75 goals+assists/90
R9 (Barca, Inter):
0,82 goals/90
0,17 assists/90
0,99 goals+assists/90
RVP (Arsenal):
0,53 goals/90
0,05 assists/90
0,58 goals+assists/90
Kane (Spurs):
0,68 goals/90
0,14 assists/90
0,82 goals+assists/90
Henry (Monaco, Juventus and Arsenal):
0,43 goals/90
0,10 assists/90
0,53 goals+assists/90
Eto'o (Real, Espanyol, Mallorca):
0,44 goals/90
0,07 assists/90
0,51 goals+assists/90
Rooney (Everton and United):
0,42 goals/90
0,22 assists/90
0,66 goals+assists/90
Let's add RVN, Messi and CR7 to the list as well:
RVN didn't play in a top five league before he was 25
Messi (Barca and PSG):
0,73 goals/90
0,32 assists/90
1,05 goals+assists/90
CR7 (United, Real and Juventus):
0,32 goals/90
0,25 assists/90
0,57 goals+assists/90
And then Mbappe (needs to be tested outside of PSG soon):
0,86 goals/90
0,42 assists/90
1,28 goals+assists/90
....and Lukaku since so many likes to compare the two:
0,53 goals/90
0,20 assists/90
0,73 goals+assists/90
I also think Haaland's technique and passing is a bit underrated. While he can be a bit clunky he also has moments of brillance in which he links up extremely well or goes past multiple defenders.
To me his lack of involvement is not really a lack of technique or ability. He magically ends up in a lot of great goal scoring positions because of instinct but he seems to lack this kind of instinct when it comes to the build up. Because no matter how you put it, when the guy has games in which he has 3-4 touches in a complete half, this is not good in a system like City's. Guardiola's football is all about positioning, creating numerical superiorities, etc. and naurally most time in a game is dedicated to recycling possession. If you effectively play with 10 men, this affects the team.
I said it when City signed Haaland: As good as he was for Dortmund, Dortmund didn't really become a better team by his arrival. From a player with such mindblowing statistics, you'd expect that he immediately elevates the team he joins. Especially when those teams lacked a real striker to begin with. But so far you have to conclude that this wasn't the case up until now. Maybe a coincidence but neither Dortmund nor City improved drastically with him in the team.
The thing is that Haaland occupies 2 defenders whereever he goes, so the "effectively play with 10 men" argument doesn't quite work with him.
You haven't included the xG and xGA values of last season. This season, City is at 37.27 xG (slightly down from 37.54 in 21/22) and 13.99 xGA (up from 9.66 in 21/22). So they're creating roughly the same amount of chances but conceding more. Their xPTS is also down to 36.7 (from 37.96). And while Arsenal has less xG and more xGA, their xPTS is very close with 35.77, probably hinting at City's better xG difference coming from a select few games instead of being evenly distributed.
I mean, you have a point with the injuries to key defenders. But by bringing in a striker who scored 21 goals after 15 games, you'd definitely expect that to be reflected more clearly in the xG statistics. That suggests at the very least that Haaland's goal output cannibalizes those of others. Which isn't necessarily a bad thing as I'm sure Guardiola won't mind if Haaland's clinical finishing means he converts more. The question is if it is sustainable - and right now the results kind of suggest that City is less consistent and have higher peaks but also lower lows both in terms of defensive stability as well as chance creation.
Defensively City has suffered a couple of key injuries and has played with many different 4s and 5s in the back this season, which has seriously hurt them. As I mentioned in an earlier post they have conceded 7 goals on penalties, corners, set pieces and direct freekicks this season, while they only conceded 2 goals (1 pen and 1 corner) from these situations last season, over 38 games. Last season they conceded 1 goal from 31 corners (that lead to a finish), 17 set pieces (that lead to a finish) and 9 direct freekicks, while they already this season has conceded 5 from 16 corners (that lead to a finish), 6 set pieces (that lead to a finish) and 6 direct freekicks. It's just silly to blame Haaland for City conceding more low xG goals from dead ball situations. When they sort out their weaknesses when defending their own bow on set pieces they will be just as good defensively as before.
From open play City conceded 0,65 G/90 from open play last season, while they have conceded 0,56 G/90 from open play this season.
Offensively you are right that they created around the same amount of chances as this season compared to after 16 games last season. The difference is that they scored 33 from 37,54 xG last season compared to 44 from 37,27 xG this season. It's hard to argue that Haalands finishing hasn't massively improved their output in front of goal.
16 games into last season Bernardo Silva was their topscorer with 7 goals, the rest of the squad had 26 goals combined. The second topscorer was Sterling with 4.
This season Haaland has 21 goals while the rest of the squad has 23 goals combined. The second topscorer is Foden with 7.
It is only natural that playing with a pure striker, ends up with him being more often in good scoring positions and a natural target in the box than a false 9. I can't see how he's cannibalizing the teams chances to a degree that hurts them.
The team as a whole has been scoring more goals than the season before, but I'm pretty sure City hasn't optimalized their style and approach to playing with him yet. So unfortunately I think City will only get better as they adapt to each other.
Compare this to the "Ronaldo-situation" last season where we ended up scoring a lot less with Ronaldo in the team and him eating up his teammates goaltallies
We scored 73 goals in the PL in the 20/21 season. Topscorer Bruno had 18 goals - rest of the team shared 55 goals
We scored 57 goals in the PL in the 21/22 season. Topscorer Ronaldo had 18 goals - rest of the team shared 39 goals.
(In the CL it was worse)
Defensively it's also hard to argue against playing with Ronaldo up top didn't effect us negatively:
We conceded 26 goals from open play in the 20/21 PL season.
We conceded 49 goals from open play in the 21/22 PL season.
This is cannibalism.
