Braga defender David Carmo is interesting Manchester United.
The highly rated defender has impressed in Portugal's top flight this season and, at the age of 21, has plenty of time to develop.
United boss Ole Gunnar Solskjaer is still looking for a left-sided defender and ESPN report that Carmo is one of the players United are showing an interest in.
The report claims the Red Devils would face strong competition from other clubs in Europe, including rivals from the Premier League.
Fiorentina and Roma both enquired about the defender in the summer but did not table any bids.
