Elanga was left out of Sweden's lineup for their 2-2 draw against Slovakia in the Nations League on Saturday.
He told Fotbolskanalen: "I always want to play, but it's Jon (Dahl Tomasson, coach) who chooses, and I'm just happy that we didn't lose the game.
"Now we have an important game against Estonia and hopefully we will win.
"I'm not worried. We have many good players. I'm just happy if we win."
