I think that translates as "the problem with Charters is he doesn't chase the ball like a demented puppy, run lots of pointless distance or lump the ball aimlessly forward when it drops to his feet".
The whole point of having a team is you have a blend of styles which compliment each other. I'd argue being a dominant header of the ball is low on the priority list for a team which passes the ball through the midfield rather than plays long ball for the majority of the time.
Also, he didn't seem to have a problem tracking back and tackling in either the Walsall game or the game he started against Morecambe in the CCU Trophy.
So heading the ball is not a priority along with pressing the ball and fitness in your great football tactics philosophy.
Along with that, a more creative midfiielder would create 6 or more goals a season for our forwards negating the need for a goalscoring midfielder.
Who exactly did you have in mind, Adrea Pirlo, cause that's who you would need to create that many assists in this league.
According to you Charters tracks back and tackles yet Mellish chases the ball like a demented puppy.
If I had to pick someone on here more biased and less objective I would really struggle.
