I feel sorry for Dier. He looked like a brilliant DM in the making last season. He may not run around like Wanayama, but there's a lot more to football than that. Potentially he offers a lot more as DM. He breaks up a lot of play through positioning rather than running about. He is also a very good distributor of the ball forward. He can roam forward with the ball. Quick and strong. A great header of the ball. We ask him to learn to play a very specialist position well -which he excels at. Then we drop him and ask him to play CB cover -which we already have more than competent CB specialist in Wimmer. I'm not surprised he struggles.
In my team he is one of first names on the team sheet at DM -week in week out. And if we tinkle him around too much, he won't be short of offers, and he will go and perform what is one of the most difficult positions on the pitch to play well, for someone else.
