I think the players are poor at everything collectively, including being poor on the ball.
They don't run enough as a team, they don't move in the right way, they don't make the right decisions, they don't read the flow of the play.
The players individually are good technically, Amad, Maz, Martinez, Bruno, Ugarte, Mainoo, Mount, De Ligt, Onana, (yes even him) Dalot, Cas, Zirkzee, and most of the players in squad have an acceptable level of being good on the ball, I am not saying they are elite on the ball, but on an individual level, they range from very good to good to Ok, only ones I think are poor on the ball are Rashford, Hojlund and to some extent Garna, (I am hopeful though Hojlund and Garna will get better, Rashford probably not) the issue is on a collective level, they are horrible, they don't open up passing lanes, they don't move the ball quickly, they don't see where is the open space to move the ball too, all of this is probably due to lack of confidence, continuous bad performances under the previous regime, also not being used to the new way of playing under the new manager.
My hope is that most the issues can be rectified through coaching and hopefully as a team they just get better slowly, I've seen some good signs since Amorim's arrival, but there is long way to go.
I also hope in the summer, players who are elite technically are targetes to elevate the overall technical level of this team, being ok or good is not enough, we need elites on the ball.
