"I used to be slightly angry, but it is essential is definitely the team's victory.
"This is football, where the coach [Diego Simeone] decides and that's that."
Gameiro has scored 13 goals in all competitions for Atletico this year, having arrived from Sevilla in July.
The 29-year-old also netted the next-fastest hat-trick in La Liga history on the weekend and he has stated that he is pleased with his recent performances.
