I've posted about this before, but progressing the ball from midfield via passing is much more effective and efficient than dribbling.
The vast majority of CMs, including Anderson and Tonali, will generate between 2-4x as much Threat from their passing as they will from their ball carrying.
The most threatening CMs for passing, eg Bruno Fernandes and Tielemans, will also generate c. 3x more threat from their passing than even the most threatening CMs for carrying ball progression eg Rice and Gravenberch.
It's kind of obvious when you think about it - a person can pass a ball much more quickly over a longer distance, and beyond tighter spaces, than a person can carry the ball with it at their feet. Also, probably especially nowadays in the Premier League, unless you are fortunate enough to play against Amorim's United midfield it is very rare you'll get loads of space in midfield through which you can carry the ball in to a dangerous area.
Take this part of Tonali's data as a simple demonstration:
He passes the ball in to the final third 5.6 times per 90. He carries the ball in to the final third only 1.0 times per 90.
And according to some on here Tonali is supposedly a decent ball carrier...
Two CMs with such a limited passing range as Mainoo and MLS would seriously hinder your ability to generate chances.
