Red Devils interested in Bayer Leverkusen duo Karim Bellarabi and Son-Heung Min
There is much interest from the Premier League in the Leverkusen pair with Arsenal, Liverpool and Tottenham Hotspur also keeping tabs, according to the Daily Star.
Son joined the Bundesliga club from fellow top tier side Hamburg in 2013 for £8m and has greatly impressed, whilst Bellarabi has been catching eyes this term.
The 24-year-old has recently been given his first cap by Germany national team manager Joachim Low.
