Cant agree with that.
The game has evolved, the ball is rarely bouncing about the middle of the park out of control, or being lumped into that area needing a big dominant figure to win it.
The ball is generally won there by forcing errors or misplaced passes or poor touches, and having a player there to pounce on that.
So it's more to do with making sure your midfield is never caught out of position, so that when the oppos have the ball we have players in the right place to close them down and be behind the ball.
CDM's in the like of the Makelele, and now Kante for example are played in systems where they just sit. They patrol in front of the centre halves allowing others to push on and then provide cover if they lose the ball. They also to some degree shield the back two and prevent balls played into the feet of strikers.
Kante is supremely fit and runs all day, he's all action but also superb at reading play and where the ball is going.He is almost always in the right place at the right time, and therfore in a position to challenge for the ball and close players down, often doing it so well that he's on them before they receive the pass.
Now it's open to question whether we need such a player in our current system (not saying we wouldn't want Kante by the way, I think he would be excellent as an all out midfielder not just sitting in the middle, as he proved for Chelsea IMHO)
The point I'm trying to make here, is that with the system Wilder favours he needs players in midfield who are fit and prepared to work hard without the ball so that they restrict the time of opponents and force errors. Then with the ball are good enough to receive the ball under pressure and have the vision and ability to spread the play and pass it quickly and accurately.
The ability to keep the ball is crucial, as it is this which allows us to make do without needing a CDM, both Coutts and Fleck can be relied upon to receive the ball in a tight space and retain possession. It's rarely lost through a bad touch or poor pass.
What we saw last season will happen again, but the only difference is that the errors from opponents will be less. So we will just have to be patient and work even harder.
In short...no CDM is required. Just cover for the two we have, whom I find myself saying again, will be and are excellent players who will show they are up there amongst the best in the championship.
If we were looking to buy 2 players with that ability to play as they do we would be needing several millions to fund it, we simply couldn't afford it.
