I suggest you look in the 80s and 90s because those types of DMs no longer exist. The game has changed. You can't have Roy Keans in your team any more because first the game is no longer that physical and second because team systems and player movement has completely changed. Nowadays if a defensive player goes to ground and does not get the ball, you're in deep trouble. An example off the top of my head is Newcastle's second goal against us this season when JT went to ground needlessly and we went from relatively having things under control to conceding an easy goal in seconds. That's why the first thing academies teach kids about defending now is "Don't go to ground. Don't commit yourself to the tackle unless absolutely necessary". There's a quote for Xabi Alonso who's one of the best in the world at what he does where he says tackling is not something you aim to do, but rather something you sometimes have to resort to. Bottom line is, all the good DMs today are the ones who know how to close down passing angles, tighten spaces and force the error.
