Bundesliga club RB Leipzig on Friday bought Belgian striker Lois Openda from French club Lens.
The Bundesliga team said on their website that the 23-year-old Belgium international had signed a five year contract and that "the transfer fee did not exceed the limits we had set for ourselves."
Lens said it was a "record fee", but did not specify which club it was a record for.
The 23-year-old joined Lens from Club Brugge for around 10 million euros last summer. He scored 21 goals, a club record in Ligue 1, as Lens finished second behind Paris Saint-Germain.
Openda replaces Frenchman Christopher Nkunku at Leipzig, who moved to Chelsea after finishing last season as joint-top scorer in the Bundesliga with 16 goals.
"RB Leipzig have a clearly defined and attacking-oriented style of play, which fits perfectly to me as a striker," Openda said on the Leipzig website.
