During today's presentation to Atletico fans at the Wanda Metropolitano, the former Chelsea striker was asked about the prospect of playing with Griezmann.
Costa stated: "I'm excited by the idea of playing again. I waited the necessary time before arriving at this moment to be able to play again.
"The training sessions put you in shape, but nothing beats the matches. I get on well with Griezmann, Torres, Gameiro, and the team's forwards in general. It's not because they have not scored for a while that I will arrive and solve everything. These are moments that happen.
"I am fit to play with Griezmann and Torres. I know there is a lot of competition, but it will be healthy competition."
