Marcos Alonso and the Genius of Thomas Tuchel - The New York Times:

There is, as ever, no such thing as a good or a bad player, only one in the right or wrong system.

His is not so much a triumph of making square pegs fit in round holes, but of changing the location of the holes so that the dodecahedrons can work, too, taking all of the raw materials he was handled — all of the players who might have thought their time was up, who might have been written off, who might have gone another way — and turned them into a purring, smooth-running machine.

The truest test of a manager, though, is to find that system, regardless of the players.

The more I look at it, the more I see the similarities between football and software engineering.
