Arsenal are chasing Olympique Marseille prospect Christopher Rocchia.
Foot Mercato says Marseille are struggling to secure Rocchia to a pro deal amid interest from European rivals.
The 19 year-old is wanted by Arsenal, where their scout Gilles Grimandi has been in contact, and Borussia Dortmund.
Rocchia has an amateur deal with OM to 2018, but has already rejected a three-year pro contract offer from the Ligue 1 giants.
"When we see the reservoir of young people who have left for these two clubs, we think that Rocchia has every chance," a confidant said of Arsenal and BVB's interest.
