I guess, as Mourinho said, people have different opinions of a box to box player.
To me, a box to box player is exactly what it says, and how Mourinho described it as. When we go forward, they should be in the opposing teams box, when we defend, be in our box. Simple as that!
However, if Mourinho is playing a 4231, and wants to play a 4231 properly, then we shouldn't need box to box players. What we need is two defensive midfielders, who are going to sit in front of the back four, break up play and play it simple.
That's what he was so impressed with McTominay for against Huddersfield.
"He's a kid that chases the ball, that tries to recover high up the pitch and when he has the ball it is always simple and against opponents like Huddersfield, so close and with so many bodies behind the ball, the simplicity sometimes is genius.
"You don't have space, you have to open spaces by playing simple, so was a decision to play the kid."
Now, neither McTominay nor Matic were 'box to box' last week against Huddersfield. They sat and distributed it simply, whilst the front four and full backs attacked. Like I said, that's the role of a double 6 pivot in a 4231, hence why it's a 4231 and not a 4411, because the front four are separated from the midfield two.
Going back to Pogba, the reason people will always see Pogba as neglecting his defensive duties is because he's obviously being asked by Mourinho to get forward when we attack and get back when we defend, but he shouldn't be.
If like McTominay and Matic he sits in front of the back four and distributes, then he won't get caught out of position. It's really that simple.
If he stays deep and uses his fantastic passing range, as we saw last week, when he picked out Mata that lead to the pen, then he can become a success, and will give us more structure. As I said before, I believe he can play a similar to the role Pirlo played at Juventus.
