Borussia Dortmund are entering the race to sign Andre Silva from Eintracht Frankfurt.
The 25-year-old has a contract until 2023, and does not have a release clause.
Frankfurt are seeking roughly €40 million to sell a player who has 23 goals this term.
Arsenal, Manchester United and Atletico Madrid also retain an interest in the Portugal international.
And according to German publication Bild, Dortmund may look to Silva if they lose star striker Erling Haaland this summer.
The Norwegian is being targeted by United, Manchester City, Juventus, Chelsea, Barcelona and Real Madrid.
If Haaland were to leave, Silva would be the ideal replacement, given his form and familiarity with the Bundesliga.
