Manchester Evening News are reporting that Manchester United are monitoring FC Porto pair Bruno Martins-Indi and Ruben Neves.
The publication claims United had scouts at Porto's match this weekend versus Maritimo. With Louis Van Gaal having so many injury problems this year, it is thought he's eyeing up Martins-Indi to finally bring an end to the saga.
Van Gaal knows Martins-Indi particularly well from his time as Dutch National team manager.
Ruben Neves is seen as more of a target for the future as the youngster is highly sought after by a number of top clubs. Neves recently won his first Portugal caps and is the youngest FC Porto player to make 50 appearances.
