Deportivo La Coruna winger Pinchi is attracting Premier League interest.
The Sun says the 22-year-old has seen his playing time limited at the La Liga club this season and is eager to search for a new challenge.
Manchester United representatives have been impressed by the youngster's progress, and are eager to discuss a potential deal at the end of the season.
Pinchi's current contract expires in the summer which means he could be available for a small compensation fee.
However it is rumoured Liverpool and Tottenham Hotspur are both monitoring his situation too.
