Yes I agree, but what is your point exactly? That it's not De Gea fault, just bad luck or something else?
I just tried to prove he's doing worse than in previous seasons and the reason we're a little shaky at the back is not because of defenders / midfielders, who seem to be doing alright.
Also, compared to previous seasons he's doing worse than expected (let's say worse than statistically average goalkeeper) basing on available data:
- 2017/18 PSxG +9,1
- 2018/19 +0,9
- 2019/20 +2,1
- 2020/21 -1,0
Which seems to be fair as it shows in previous seasons he was above average, but doesn't seem to be the case this season.
