The 23-year-old was playing up front for the Blues after manager Antonio Conte made five changes for the encounter with the Azerbaijani side and Batshuayi was duly among the goals, grabbing the fifth of the night and his first in the competition.
"It was good for the team," Batshuayi told the Chelsea website. "The clean sheet also and for me and for Marcos Alonso, Davide Zappacosta and N'Golo Kante, it was our first game in the Champions League and to win the first game is very good.
"You know I don't play every game but when I have time [on the pitch] it is good to score.
"No game is easy in the Champions League. Every game is a good game so you stay focused to try to win every game. Now I concentrate on the next game with Arsenal and to train well and try to win the game."
Batshuayi has made three Premier League appearances for Conte's side so far this term, all of them coming as a substitute.
