Spanish correspondent Sid Low provides more detail on de Gea's omission from the Spain squad.
"This week, the Spanish football statistician Alexis Tamayo offered up seven metrics by which to measure goalkeepers. In all seven, David Raya was ahead of David De Gea. Bringing them together to create a "score," the ranking read: Raya 85%, Sánchez 79%, Simón 55%, De Gea 54%. No, it's not just a number -- still less than an exact science, but there is something in that."
"Which metrics those were are significant, too. It's not just the saves (totals, per shot and per goal), but also catches, punches clear and challenges won. Some keepers prevent themselves from having to make the save by ending the move sooner; that simple idea of
dominating the area matters. In Luis Enrique's vision, a goalkeeper can't just stay on his line, however brilliant they might be there. And then there was one other metric, which at the risk of becoming reductionist was probably the most important of all, way ahead of actual goalkeeping: passes."
"Luis Enrique is a coach for whom a goalkeeper has to be a player too, someone who must make saves, but must start moves too. It's no longer such a revolutionary idea, of course, and he is hardly unique, but for him it is absolutely non-negotiable."
"The goalkeeper is not there just to save it, at least with Luis Enrique," Unai Simón told El País in a fascinating interview. "You have to find the free man, which is often me, and if the opponents come to press me that means there's someone else unmarked. It can look risky, but it's studied and worked upon. Are you scared to have the ball? You shouldn't be because that's how we play. If it goes wrong sometimes, no problem because you have to take risks. Luis Enrique has made me and the team see that."
