I agree, it doesn't tell you much. DCL had like 12 passes to him the entire game and only got 2 touches in the box. Interestingly enough, he got WAY more passes to him against Villa than he did against anyone else. He received 3 passes against Watford. 3. But Sigurdsson only got 7 against Watford because he was playing as a second striker, so these things have to be understood within context.
I also recognize Richy is out of form, but that's the side Gylfi was playing on. Marco had him WAY over to the right both deeper to help with building out of the back and overloading that side to work with Coleman and Richarlison. I mean, the guy sprung Richy for what should've been a PEN, played Coleman through wide open, made some pretty nice smart passes to get Richy out in the open, a couple that turned into shots - not good ones, but shots nonetheless, he was pretty good playing deeper. Got a lot more touches, too. We created little as a team in the first half, yet he was clearly disproportionately responsible for what was created.
Conversely, Bernard had 5 forward passes the entire game and completed 3. Does that mean he wasn't any good? Maybe. Is he a bad player? Of course not. But he got the ball just as much as Sigurdsson did and did much less than what Siggy did with it. But for some reason Siggy gets killed for it. Just seems like a double standard.
