Victor Boniface scored his fourth goal in the UEFA Europa League for Bayer Leverkusen at BK Hacken to win all five group games thus far.
The Super Eagles striker opened scoring for his Bundesliga club in the 14th minute to inspire them to a 2-0 victory in Sweden.
Last season, he finished top scorer in the competition with six goals for Belgian club Union St.Gilloise.
Leverkusen are runaway winners of Group H and have thus advanced to the Round of 16 of the competition.
Chuba Akpom was also on the scoreboard for Ajax in the Europa League.
He scored with a diving header at Olympique Marseille.
However, a 4-3 loss in France has knocked his Dutch club out of the Europa League as they are bottom of the standings with two points with a round of matches to be played.
