yeah, it's not a rule that midfield leaders transform into great coaches, but many of the elite level coaches used to be midfielders, off the top of my head Zidane, Conte, Guardiola, Allegri, Capello, Wenger so I always look at former midfielders that start to coach with more enthusiasm than former strikers or defenders. but of course from the great midfielders of the previous gen like Pirlo, Lampard, Gerard, Arteta, Xavi, Xabi, etc maybe 2 in the end will turn out to be great coaches.
