Arsenal have reportedly been told that they will have to stump up Antonio Sanabria's full release clause if they are to prise him from Barcelona.
The 17-year-old has been linked with a move to North London after stating his intention to leave Camp Nou, although Italian side Roma are also believed to be in the hunt.
According to The Mirror, Gunners boss Arsene Wenger is keen to land the Paraguay international, but will have to part with £3.6m for the young striker.
Sanabria, who won the first of his three international caps in a 3-3 draw with Germany in August, currently plays for Barca's B team.
