Aragones was also the creator of the Golden Generation of the Spanish National Team which ended up winning a World Cup and two UEFA Euros. The first one under Luis Aragones in 2008.

Furrthermore, Diego Simeone is also the winningest coach in Atletico Madrid's history with his eight titles. As he reached this incredible milestone, Simeone went to social media and dedicated an emotional letter to Luis Aragones.

"Dear and eternal Luis. I know Atleti was your life and you know that Atleti is also mine. That's why I didn't want this moment to pass unnoticed, because I know today you're the only one who can understand me. You know I'm not a fan of these things, expressing and sharing in public this type of emotions, but today I want to do it. I do it with tears in my eyes and a huge feeling of emotion, but above all, of respect."
