The transfer fee for the 22-year-old footballer could be around 70 million euros, which would make it the most expensive acquisition of the Forties in the club's history.

The transfer will be officially announced once the final details have been agreed between the parties, but personal terms with the player have reportedly already been agreed. The Basques insist that the deal includes a clause for 10 percent of the future sale of the Swedish forward.
