Arsenal are watching Malmo youngster Filston Mawana.
The 16 year-old is expected to leave MFF in January and has been offered trials by Sporting CP.
Arsenal and Juventus are also watching the youngster.
"It is true that Sporting invited Filston and that the clubs you mention follow his development," agent André Filipe Jenaro told fotbolltransfers.com.
"He has developed a lot in recent years and progressed with Malmo FF and the national team."
