The 18-year-old was signed by United last summer from Universidad de Chile and then he was loaned out to Roberto Martinez at the DW Stadium, supposedly to get some experience in the English Premier League.
But the player has appeared just five times for the Latics and this has cost him his place in the Chile squad he feels. Now he wants another club so that he can prove his worth and get back into the international scene.
The teenager is reportedly after a move to either a Championship or Spanish club.
