Berlin - Spanish striker Paco Alcacer is set to make his loan deal at Borussia Dortmund permanent, according to reports in German media on Friday.
The 25-year-old joined Dortmund from Barcelona on a one-year loan deal in the summer and has made in immediate impression with eight goals in just six Bundesliga appearances, including the winner against Bayern Munich two weeks ago.
Bild newspaper and Kicker magazine reported that Dortmund, who have built a four-point lead at the top of the Bundesliga, have offered Alcacer a contract until 2023 with a transfer fee for Barcelona worth upwards of €21 million.
That could rise by a further €5 million in bonuses.
The deal is expected to be announced formally by Dortmund after Saturday's away trip to Mainz.
