Okay thanks.
Using that site here are some basic stats from this season of attacking players with over 100 minutes so far:
Goals + Assists per 90 VS Expected Goals + Assists per 90
Gabriel Jesus (171 mins): Has 2.11 G+A (0.54G + 1.58A), was expected to get 1.01 (0.33G + 0.68A)
Jesus is out performing his xA massively which usually means the opposite unlike xG. Out performing your xG means you are scoring chances that others typically don't. Beating your xA means people are scoring goals from your assists that players typically don't, it's a combination of crediting the striker for scoring and perhaps the chance not being THAT good (hard to discern which exactly that's why I said combination).
This kind of makes sense because while I like Jesus RW, I think the team has been a little lucky with scoring from his crosses, not that they weren't good, they just weren't THAT good (KdB level on a plate).
Riyad Mahrez (124 mins): Has 1.46 G+A (0.73G + 0.73A), was expected to get 1.41 (0.83G + 0.58A)
Nothing to say here, he is pretty much exactly inline with his expected stats.
Raheem Sterling (132 mins): Has 0.68 G+A (0.68G + 0A), was expected to get 0.94 (0.87G + 0.06A)
Underperforming his expected stats. His expected G+A is close to Jesus (0.94 vs 1.01), but Sterling leaning WAY more into goals and Jesus into assists.
He has to pick up his scoring, very early in the season of course, so let's hope he does, because as we can see, Sterling does not create like our other players (perhaps why playing him striker is better).
Jack Grealish (254 mins): Has 0.70 G+A (0.35G + 0.35A), was expected to get 0.74 (0.37G + 0.37A).
Same as Mahrez in that he is inline with what is expected. That being said, the lowest expected return of the 4 so far but he is new to the team. All these xG+xA are a little skewed right now btw because of the 10 goals scored recently (everyone's will go down this season).
Ferran Torres (240 mins): Has 1.12 G+A (0.75G + 0.37A), was expected to get 0.65 (0.64G + 0.01A).
Outperforming his xG by a bit. The assist is for the pass to Rodri that typically doesn't go in, hence why is xA is so low but he is credit with 0.37A/90. He is a good playmaker on the wings with his crossing, but hopefully he can develop some more in central positions.
Very early stats based on limited minutes. But thought it was a little interesting nonetheless.
Can update a couple months later to see how they are doing.
