The Uruguayan was a surprise arrival in the summer transfer window on deadline day.
While he has impressed coaches in training and during under-23 games, he is not quite ready for meaningful first team minutes.
Now his agent Edgardo Laslvia says the player may move on loan to a Spanish club.
He as told Fichajes: "We are working on that (a transfer), surely Spain is the destination."
Any loan move is not likely to impact his long term future as United.
