The Liga-winning manager is thrilled with his side after a 1-1 draw that clinched a title.
Atletico Madrid coach Diego Simeone thanked his players after they won La Liga with a 1-1 draw at Barcelona on Saturday.
Needing just a point at Camp Nou on the final day of the season to claim its 18th La Liga title, Atletico found itself behind at the break.
Alexis Sanchez fired the Catalan giants in front in the 34th minute after Atletico had earlier lost star striker Diego Costa and midfielder Arda Turan to hamstring and pelvis injuries respectively.
But Diego Godin's second-half header ensured the visitors claimed the draw they needed in a dramatic second half that also saw Lionel Messi have a goal ruled out for offside.
"It's amazing," Simeone said. "You can't explain it. Thanks to the players. We've never stopped working and that's why we're here. Today is one of the best days in the history of Atleti.
"I'm sure (former coach) Luis Aragones (who died earlier this year) was defending for us in the second half."
Goalscorer Godin revealed his side was inspired by words of wisdom from Simeone at the break.
"We've fought all year and done an amazing job," Godin said. "To hold off Real Madrid and Barcelona has been difficult.
"Simeone told us at halftime that we were definitely going to score and justice was done."
