The hub of most teams is the midfield but for Mauricio Pochettino it is perhaps the true epicentre to success. Just like the rest of his coaching identity, there is a demand for total buy-in and commitment to the cause. The same may be true for all top teams but Pochettino in-particular places physical demands over tactics in a way.
It is his belief that you can outwork a team even when you can't out-tactic them. The very basics of the game are evident when his sides play at full intensity. It could, in some ways, be compared to Jurgen Klopp's identity via intensity mantra.
To go with that there are few better as a midfield powerhouse than N'Golo Kante. His unique skillset make him one of very few players that can operate in midfield like he can. His relentless energy, speed on the press and ability to read the game and anticipate passes and angles is practically unrivalled.
