This thing about us failing to score against teams that sit deep is massively exaggerated. Teams have been defending deep against us for the past 4 years and we find a way to score almost every game. This was just the 2nd time we've failed to score this season. Man City, the side most will say is the most creative in world football have failed to score 4 times this season. Other than last season, where everything that could go wrong for us did, there's been no noticeable difference in our failure to score in games than there's too.
The problem for us is because of the way we play, with typically a workman like midfield and relying on our fullbacks for creativity, when we don't break teams down it's really not pretty. Everything becomes very very scrappy and desperate.
I get that most supporters want and expect perfection but at some point you have to realise that's not possible and there are consequences for everything. What makes a team very good in one aspect means they're not going to so good in another. Part of the reason why City are so creative is because they don't play with a number 9, the consequence of that is there will be times where they create but just don't score. Part of the reason why Salah, Mane & our fullbacks are so effective is because we don't play with a wide open, creative midfield.
