Bild claims Sevilla will buy Ciro Immobile outright from Borussia Dortmund after his goal against Real Madrid.
The Italy striker arrived on loan over the summer after a difficult debut season in the Bundesliga.
According to German newspaper Bild, the terms of the deal meant Sevilla would make the move permanent after his fifth appearance in La Liga.
That target was achieved at the weekend in a 3-2 win over Real Madrid, where Immobile also found the net.
The cost of the transfer is believed to be worth €11m plus the €3m for the loan spell.
