For all of the comments blaming the trauma of the summer and missing the penalty, it completely misses the point.
Rashford's workrate is simply not good enough for a top level footballer. When he was on form, his offensive output barely made up for it but when he's not producing offensively, he is a massive liability.
You see the workrate of genuine attacking star players like Salah and Mane and any of the attacking players at City and he's not even in the ball park. This is what puts so much pressure on the midfield 2 to cover and stretches the defence.
Last season there were excuses that his workrate was down due to injury but it's been the case for more than 2 years now. It's not an anomaly. That is just how he plays.
I found these tweets interesting from the other thread:
The language is both interesting and telling.
I am embarrassed. I am a United fan. I am delighted to have got on the scoresheet.
But, WE need to improve.
It's basically, "I'm doing all I can and am being let down by everyone else". I get the impression that mentality is rife throughout the squad just now.
The best way to improve is hard work. That's an individual, not a collective thing. Rashford does not work hard, on the pitch at least. If you could see him put the effort in on the pitch, those tweets would seem less pathetic.
The first thing everyone at United needs to do is look at themselves as the problem and ensure they are putting in the required level of effort for the team to win. Finger pointing and blaming everyone else is a loser mentality and that's where the club is at right now.
