The team is a lot worse, and we were bad enough last season! Also, the bigger the sample size, the more likely you are to be able to draw a more accurate assessment of how good a player is anyway. Also, the longer a player is here, the less people are willing to make excuses for them, so it could just be you seeing things differently. If this were last season, this thread would almost certainly be full of mitigation due to age, new team/league, previous injuries etc. The performances themselves could be identical to this, just viewed through a different lens.
I don’t think there’s a huge amount of difference between either season. It’s all perception. If Hojlund musters up a scoring run between now and May and makes it to double figures, there will be people saying that this has been a very good season anyway, which is what happened last season. So as bad as he’s been so far, if the number ends up as something we can spin, people will spin it. I think he’s got 5 in the Europa League and 2 in the league. If he can get to 10 in the league, I guarantee many will simply say ‘he got 15 last season which is a good number for a young striker’. I repeat, the same happened last season.
