Barcelona are keen to reunite Nico Williams with Lamine Yamal at the Nou Camp next season following their impressive performances as Spain won Euro 2024.
The pair were two of Spain's standout players during their triumphant campaign in Germany; Williams ended the tournament with two goals and one assist, while Yamal - who only turned 17 a day before the final - contributed one goal and four assists.
Athletic Bilbao are determined to keep hold of the 22-year-old amid Barca's interest and that of other top clubs in Europe.
However, his fee may be an issue for the Catalan club, as he has a buyout clause that is thought to be £53m (€63m).
Bilbao have also proven they can compete with the top clubs in Spain in terms of wages, having recently tied-down other Spain internationals to new contracts, such as goalkeeper Unai Simon.
