Bayern Munich star Thomas Muller.
According to Karlheinz Wild of Kicker, via Jamie Anderson of the Daily Star, "the Red Devils haven't given up hope of signing the striker, and are busy preparing a £136,000 per-week deal."
The German international enjoyed a phenomenal campaign last year, netting 21 goals in all competitions, as well as laying on 13 assists.
