Atletico Madrid forward Kevin Gameiro admitted he was "angry" after being substituted in his side's win over Bayer Leverkusen.
The France international set up a first-half goal for Antoine Griezmann and netted a 58th-minute penalty in Atletico's 4-2 victory in the Champions League last-16 opening leg.
But he was taken off with 19 minutes remaining at BayArena, much to his frustration on Tuesday.
"Yes, I was angry because you want to play the whole match when you're playing well," Gameiro said, via Marca.
"I was a little bit angry, but the most important thing is 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 season, having arrived from Sevilla in July.
The 29-year-old also netted the second-fastest hat-trick in LaLiga history at the weekend and said he was pleased with his recent performances.
"I feel good now physically and mentally," Gameiro said.
"We played a great game and scored four goals that are very important for the return leg."
