Nigeria forward Victor Boniface will be leaving Belgian side Union Saint-Gilloise to join Bayer Leverkusen on a five-year contract, the Bundesliga club said on Saturday.
Leverkusen did not give any more details, but German media said the 22-year-old had joined for a transfer fee of about €20 million.
Boniface scored six goals in the Europa League last season, one of which was against Leverkusen in the first leg of the quarterfinals.
"He will help us improve the quality of our squad for the large number of games in the Bundesliga, DFB Cup and the Europa League," Leverkusen sporting managing director Simon Rolfes said.
Leverkusen finished in sixth place in the league and secured a spot in the Europa League group stage.
