It's nice to find people who understand what they are watching buried amongst all the crap every now and again.
I 100% agree with your analysis. In my opinion, the lack of aggression and defensive capabilities demonstrated by the forwards is the biggest reason for our struggles this season.
The defence and CMs have done their part by playing higher and more aggressively yet they are let down time and time again by their colleagues in the attacking positions who leave them exposed - then guess who gets all the blame after the games...
Likewise, De Gea is 'cheating' his teammates in my opinion, playing a game which suits his style to the detriment of the others. At least Henderson tries to help his back four. DDG seems only concerned with what's best for him.
Again, guess who then gets praised after games and labelled as having a "great season".
It wasn't such a big issue last season because we weren't quite so high and quite so aggressive, particularly in away games or games against the top six.
Of course, you can debate how good some of our players are, personally I wouldn't claim McTominay, Fred and AWB, for example, are "elite"...but they are certainly 'good enough' to finish top four when playing in a cohesive team with a defined structure.
