Manchester United are watching Benfica fullback Nelson Semedo.

The Daily Express says United scouted Semedo during Benfica's Champions League clash with Napoli on Tuesday.

Semedo has established himself as one of Portugal's hottest properties - helping his club to the top of the Primeira Liga table.

The full-back's fine performances mean that Europe's big boys are beginning to monitor his situation.

Diario de Noticias reports United scouts were in attendance on Tuesday to watch him in action.

Though the 23-year-old impressed, he could not prevent Benfica from falling to a 2-1 defeat.

It is also said that Semedo has a huge buyout clause worth £50million.
