Striker easily.
It's by far the most important position we need to invest in.
I genuinely believe our defence and midfield have been phenomenal this season ( starting, not depth).
However, our attackers have been so bad that despite massive improvements in our general play and solidity, we haven't been able to take advantage.
Our attack is the reason for our away record.
Our dominance, solidity and experience carries us in home games where we can easily shut down the opposition from scoring.
But in away games where we can't expect to dominate the midfield battle, we don't have enough offensively to carry us. Our current team can't win 3-2 away from home; they can barely scrape out a 2-1.
This is because if Bruno, Eriksen, Casemiro or Shaw aren't involved, unless Rashford has a moment of magic, nothing is happening. In away games, particularly against the better sides, where the individuals mentioned above may be pushed deeper, our attack literally becomes a black hole.
This didn't start now. It's been a problem for years.
Our attackers outside of Rashford don't actually attack. ( Bruno is a midielder)
The job of the midfield is to provide attackers with the ball in the final third of the pitch. United this season has done that to a very consistent degree, both home and away.
The problem we have is that when they do get the ball in these positions, they don't do anything with it unless they have countless time and space. The irony is, they should be creating time through their ability to keep the ball, space through making runs for teammates, attacks through dribbling, winning duels through intensity and speed of thought. I don't expect our current attackers to keep the ball when faced with any real pressure high up the pitch. But this is something that if you watch Liverpool or Arsenal, you seen their attackers contend with and deal with really well. Ours either lose the ball or give up on the attack by passing back to safe zones. For anything to function in attack, Bruno in particular has had to put things on a plate for our attackers. Yet somehow, despite this effort, he gets more criticism from fans because he's actually active. Antony tries, his decision making hasn't been great and he's just started to get a bit more comfortable. The issue we have on this team has been having to consistently play the likes of Martial, Weighorst, Sancho and Elanga in attacking positions. So poor that we've had to shuffle Bruno all season to cover these positions.
The point here is that attack will always be the most important part of the pitch. Ours haven't been doing it for a long time, so it feels like our fans have forgotten how much an attacking player should actually be showing for the ball. We used to dominate the league because we had countless attackers, both starting and in depth who used to consistently run oppositions ragged through their footballing ability, skill and technique. People here have said a player like Martial was quality in the past, despite him being completely unable to use his weaker foot. Playing to his right is almost impossible for him, which is why he can't play on the right wing. He literally has to dribble around at times to change directions, yet people here were convinced of him being a dribbling wizard, when I can watch Bernardo Silva or Martinelli make a quick turn in a single second. We have low standards for our attackers and we don't notice it.
