Borussia Dortmund have activated their option to sign Paco Alcacer from Barcelona on a permanent contract until 2023.
Alcacer, 25, who joined Dortmund on an initial one-year loan, will officially become a Dortmund player when the transfer window reopens in January in a deal which Barcelona announced is worth €23 million, plus €5m in add-ons.
Barcelona will receive five percent of any future transfer profit should Alcacer, who has scored nine goals in eight games for the Bundesliga leaders, move to another club.
"Today, we informed FC Barcelona that we will trigger the buy option," Michael Zorc, Dortmund'a sporting director, said in a statement. "Paco is here at Dortmund with his heart and soul. He settled-in in a very short period and has become a permanent fixture in our squad.
"I am convinced that Paco is a 100 percent fit for us."
Alcacer added: "I am very happy in Dortmund, at BVB and in this wonderful squad. Borussia Dortmund has been and is exactly the right decision for me. I will do all I can to pay back the trust in performances and goals."

In addition to Alcacer, Dortmund had a busy summer in the transfer market in signing Belgium midfielder Axel Witsel, Denmark international Thomas Delaney, defender Abdou Diallo, winger Marius Wolf and keepers Marwin Hitz and Eric Oelschlaegel. Full-back Achraf Hakimi joined on a two-year loan from Real Madrid.
They are expected to offload fringe players such as attacker Alexander Isak and midfielder Sebastian Rode in January but have ruled out selling United States captain Christian Pulisic.
