Mikel Arteta has made Athletic Bilbao's Unai Nunez his top transfer target as he looks to overhaul Arsenal's defence for next season.
The 23-year-old has a release clause of £26.45million and, according to La Razon via Deia, the Gunners are prepared to meet it.
However, it's a price several clubs are thought to be willing to match with the release clause seen as relatively low for the current transfer market.

Nunez has made 18 appearances in all competitions for Bilbao but it took him until the second half of the season to nail down a regular starting place.
