Falcao joined Ligue 1 juggernaut Monaco at the start of the season for a fee believed to be worth €60million, ending his two-year spell in Madrid.
Many had tipped Atletico to struggle following the departure of the star striker, who netted 52 goals in 68 La Liga appearances.
Speaking to Spanish newspaper Mundo Deportivo, Falcao said he was 'very happy' with the situation at the Vincente Calderon.
"I don't have any envy of Atletico," the injured Colombia international said. "I feel mostly very happy for what is happening at the club.
"I made some great friendships and had some important moments while I was there.
"It's life, in the life of a footballer you have changes and you can't have everything.
"I am very happy for what they are doing and I want the best for them."
Meanwhile, Falcao talked up Mario Balotelli's potential switch to Monaco after the Italian striker was again linked with a transfer away from AC Milan.
"I think Monaco have a very ambitious project and it's normal for us to be linked with names like Balotelli," said Falcao, who has continually been touted as a target for Chelsea.
