Arsenal boss Mikel Arteta blocked the club from making a summer move for Emerson Royal, according to reports.
The Gunners were reportedly keen on signing the 23-year-old from Barcelona in August as they frantically searched for a new right-back.
The club's technical director, Edu, had already contacted the player to establish a relationship with talks said to have been in an advanced stage as the analytical department had given their stamp of approval.
