Premier League scouts were in attendance for Austria's Nations League defeat against Denmark.
Manchester United's scouts made checks on Christian Eriksen and Konrad Laimer during Denmark's 2-1 victory against Austria on Monday.
New Red Devils boss Erik ten Hag wants to sign Eriksen following his fruitful spell with Brentford since January, especially as his short-term contract expires at the end of this month.
And United were one of the teams named on the scouting list during Denmark's Nations League clash in Vienna, alongside fellow Premier League outfits Tottenham Hotspur and West Ham.
RB Leipzig midfielder Laimer has also been linked with United in recent weeks.
