A Kai Havertz brace inspired Bayer Leverkusen to a 4-1 win over Werder Bremen to move fifth on the Bundesliga standings.
After a quiet opening 25 minutes, the match sprung to life when the youngster opened the scoring after 28 minutes, converting a Kerem Demirbay ball for the lead.
The hosts, however, hit back two minutes later, with Gebre Selassie bundling the ball home from close range from Bittencourt's corner for their first home goal since December.
It, however, took the visitors three minutes to restore their lead, as Havertz rose highest to meet Demirbay's nicely whipped ball from a freekick to head past the keeper.
There was little action in the remaining minutes of the half as the visitors took a comfortable lead going into the break.
The hosts tried to hit their opponents from the onset of the second period, threatening them time after time.
They came closest on the hour-mark but the visitors cleared their lines quickly and sent the ball out of play for a throw-in.
They were however undone almost immediately as Leverkusen scored a third, this time Mitchell Weiser out-jumping everyone to powerfully bury a header for a 3-1 lead.
With some breathing space, the visitors opted to control the match from midfield and were happy to run rings around the hosts, who seemed lost.
They were punished even more on the 78th minute as the brilliant Kerem Demirbay beautifully looped over the goalkeeper after a wonderful through-ball from Karim Bellarabi for a 4-1 lead.
The win saw Leverkusen move to fifth on 50 points, one behind fourth-placed RB Leipzig.
Werder Bremen, on the other hand, recorded yet another defeat, sinking further into the regelation mud.
