Torres has won everything. The Champions League, the European Championship and the World Cup, but never had he won anything with Atletico.
He deepest ambition was always to win something with his boyhood club, but he was absent for all of their wins early in the Simeone years, when they conquered La Liga and the Copa del Rey.
He can now add the Europa League to everything else. It certainly isn't the biggest trophy he has won, but it will have huge sentimental value.
He has supported the team since he was a child, and they have always been in his heart even when he was not playing in Spain. It is impossible to forget Torres wrapped in an Atletico flag after his wins with Spain.
He is an idol for all the fans of Atleti, an icon of the club. He is leaving at the end of the season and he can leave in the way he always wanted: with the pride of having finally lifted a cup with his team.
