It marked a winning start for Atletico at the Estadio Wanda Metropolitano.
"We really wanted to win, we trained here on Thursday but something was missing, the No. 12 [the fans] was missing," he explained to the assembled press.
"The truth is, it is the best stadium I've played in, and not just because it's our home."
Atletico have been without their star forward since the LaLiga opener through suspension and Griezmann was eager to make clear just how determined he was to get back to football.
"I really wanted to get back to running and working hard for the team, I am very happy to be able to do this again," he added.
"And with every match I feel better."
