Actually this is interesting:
Last season in 50 games we scored 50 goals and conceded 56.
This season in 36 games so far we have already scored 64 goals and conceded 49.
So in 14 games less we scored 14 goals more. This is huge difference. But with 13 PL games left and one more at least in Cup it is clear we will concede more than last season.
So imo defense has not been good at all even last season but this season it is even worse. But by the look of it Poch improved our attack and this is still with Nkunku out for most of the season.
Last season best goalscorers had: 9, 9, 4, 3 goals.
This season they are on: 12, 10, 8, 7, 5, 4, 4. So much better and like I said still plenty games to play.
