Athletic Bilbao winger Nico Williams is being linked with a move to the Premier League.
The tricky winger is the younger brother of long-time Bilbao star Inaki Williams.
The 21-year-old did put pen to paper on a new deal last year, which increased his release clause.
However, The Mirror states that Arsenal have been consistent in sending scouts to watch him.
They are not the only club serious about Nico, as Real Madrid, Aston Villa, and Liverpool are also in pursuit.
Arsenal are ready for a mini squad revamp in the summer, with Thomas Partey, Emile Smith Rowe and Eddie Nketiah likely to go.
