Manchester United scouts were posted to Benfica's win against Portimonense yesterday.
O Jogo says United had scouts see Benfica thrash Portimonense 5-1. In their sights were Benfica pair António Silva and Gonçalo Ramos.
Defender Silva and striker Ramos are both under consideration at Old Trafford.
United requested accreditation for yesterday's clash between the Eagles and Alvinegros and their scouts were present in the stands.
It's suggested United would be willing to offer as much as €115m as a package for the pair.
