I agree that such results happen. But I think that because the Fulham game was played recently it weighs a lot. By the end of the season its overall effect will be weaker. My expectation is that we are going to concede around 33 goals. That is, we are likely to improve in the 2nd half of the season.
Note that in the first 3 games we played without Donna, Gvardiol and O'Reilly, and we have played mostly without Rodri. So there's room for improvement.
We have conceded 12 goals in the last 12 league games, including the shitshow at Fulham.
