United have the highest number of touches per game in the defensive 3rd of any Premier League team, 6th in middle 3rd touches and 10th in final third touches. So with all due respect, this clearly isn't capturing the problem. We don't get the ball out from the defence into midfield quickly enough, the balls gets stuck being circulated around the back 5 and teams either win it back with their press or drop back into their defensive shape. It's why we struggle to score goals. We look like a relegation team when the ball gets to the forwards because we simply don't get the ball out of the back very often and when we do it's usually very slow.
The top 5 teams for touches in their own defensive 3rd are United, Brentford, Southampton, West Ham and Spurs (with Leicester in 6th). The bottom 5 are Arsenal, Bournemouth, Forest, City and Everton (with Liverpool, Villa, Newcastle and Brighton immediately after them). Even if you look at it in terms of percentages (which has it's own issues), we're 10th/12th/14th, surrounded by a whole glut of really bad teams. We're in the wrong group there and it's very obvious in our play.
So yes, we desperately, desperately do need a midfielder who can actually break a press and get the ball forward quickly. Mainoo and Ugarte are frankly terrible at progressing the ball from deep, Casemiro is our best at is, but he's erratic and get's caught by pressing players on the half turn way too often (which is why Madrid always played Kroos as the first receiver from the defence and not Casemiro). Bruno simply shouldn't be playing there unless we're playing against a team with no intention of pressing and just looking to defend in 2 banks of 4/5, he's better in attacking positions and we're robbing Peter to pay Paul by dropping him back.
