On-loan at BVB to the end of the season, Batshuayi struck the only goal of the game in victory over Hannover.
He said: "We really wanted to make the three points.
"I saw that Hannover had a lot of players in defence. Then I made the track like a striker and hit the ball well into the goal."
Batshuayi has now scored six goals in seven Bundesliga games for BVB.
