Bruno and Diogo Dalot are currently representing Portugal in Qatar, where Fernando Santos’s side have reached the quarter-finals.
Schweinsteiger believes Portugal’s team is talented, and that United’s players are contributing to their success.
“I saw them against Switzerland, when they beat them 6-1,” he said of one of the favourites to go all the way in Qatar. “He [Fernandes] played amazing and it’s also interesting, Dalot was doing a great job as a full-back there. [He was] working hard and pushing forward as well, but he does, first of all, the defensive work.
