I love this post and it is spot on
We.absolutely need a dominant midfielder, we have for 3 years. This would clearly help massivley. However, I'm going to simplify your post because I believe that having 2 quality wingers would mean that all the above problems would be solved.
Basically, quite rightly no one (players or fans) has confidence in elghazi or trez.or.traore. If we had 2 quality players in these positions and Grealish as a 10 it would allow these players to receive the ball, retain the ball and make.something happen. The full backs would push on with confidence. We would attack with purpose. The problem would be solved.
