Chelsea and Tottenham have been monitoring Garnacho’s deteriorating situation at Old Trafford, and Villa are understood to have registered their interest in the 21-year-old Argentina winger.
Atletico Madrid have also been linked with their former academy player, and United rejected an approach from Napoli in January, but Garnacho is said to be keen to stay in the Premier League.
He has been training away from the first-team since returning to Carrington last Thursday when he worked out with Marcus Rashford, another member of the five-man bomb-squad.
While United would consider loan moves for Rashford, Jadon Sancho, Antony and Tyrell Malacia, they are hoping to sell Garnacho who would generate maximum profit under financial fair play rules.
