Toni Kroos
If the Red Devils could land the brilliant German international, there would be a fresh wave of optimism around the club. Although Kroos is a key member of an outstanding Bayern Munich squad, 24-year-old midfielder is yet to sign a new deal with the club and could be sold for a hefty fee this summer.
Kroos is a class above the likes of Michael Carrick and Fellaini, and is a player who could replicate the kind of timeless display Ryan Giggs produced last night against Olympiacos.
