Manchester United are watching Francisco Trincao's situation at Barcelona.
Sport reports Trincao is set to be sold this summer by Barca, with funds needing to be raised to help secure Lionel Messi to a new contract.
The former Braga attacker's availability has already sparked interest from across Europe.
AC Milan and Juventus are watching developments, while football chiefs at United have also been alerted to Trincao's potential sale.
Inside Barca they regard Trincao highly, but believe he can be sacrificed in order to help balance the books this summer.
