Manchester United are watching the progress of Andre Silva at Eintracht Frankfurt.
The former AC Milan striker has scored a stunning 18 goals in 20 Bundesliga games this season and his form has attracted interest from Atletico Madrid.
However, Sky Deutschland says Silva's goalscoring has also caught the eye of United.
United see the Portugal international as an alternative to Borussia Dortmund star Erling Haaland and believe they can sign him for around €30m.
Under contract at Eintracht until 2023, Silva saw a winter approach from Atletico rejected by sports chief Fredi Bobic.
