By the end of that season, the club had won the Europa League and the next, the Copa del Rey. In 2014, Atletico won La Liga for the first time in 18 years.
The team’s success did not dampen the fire in Burgos’ belly. In 2012, he told Jose Mourinho during a heated Madrid derby: “I’m not Tito Vilanova. I’ll rip your head off.” Mourinho had once poked Vilanova, the former Barcelona coach, in the eye.
But Burgos’ hard tactical nous and the trust he shares with Simeone has been key to Atletico beating bigger, more established rivals.
It is Burgos’ job to analyse opponents and a few minutes into every match, he describes to Simeone the other team’s formation and positioning.
Burgos became one of the first coaches to wear Google Glass during a competitive fixture in 2014, as he had live statistics from the game in front of him fed in every 30 seconds.
When Simeone decides to leave Atletico, it has been suggested his assistant would make an excellent successor. Burgos will be given a taster in Lyon on Wednesday.
“We have Burgos,” Simeone said, after missing the semi-final second leg against Arsenal. “We don’t even need to look at each other to know what we want.”
