Manchester United are working on a deal to sign highly-rated Poland youth international Ariel Mosor when he attains the age of majority.

Polish agent Dominik Jarosz has informed through the social networks that Mosor has been training with the Red Devils for the past one week, with a view to penning a contract in future.

''Ariel Mosór, a young Polish national team, has already spent one week at Man Utd Academy! 😈💪 Further valuable experience, step by step. 👊,'' Jarosz tweeted.

Born February 19, 2003, Ariel Mosor, who is a midfielder, captained the U14 national team of Poland before he was promoted to the U15s.

Another Poland youth international Łukasz Bejger trained with Manchester United last August.
