If the Blades, who have a highly favourable fixture run-in compared to some of their divisional rivals, can pull off the feat of qualifying for European football, they'll be looking to attract a similar calibre of player in the summer. Here's a look at nine other Champions League hidden gems United could look to sign...
5. Hans Vanaken - Club Brugge
A big fish in a small pond, the Belgian midfielder looks ready for the step up to the Premier League. He's a gifted midfielder with eagle-like vision, and he contributed a whopping 14 goals and 17 assists last season. (Photo by KURT DESPLENTER/BELGA MAG/AFP via Getty Images) Photo: KURT DESPLENTER
6. Mady Camara - Olympiakos
Here's an option already believed to be on the Blades' radar, following some stellar showings for the Greek side. He's a physical force to be reckoned with, and would add some more grit to United's midfield. (Photo by BEN STANSALL/AFP via Getty Images) Photo: BEN STANSALL
7. Amadou Haidara - RB Leipzig
Brought in to leave the sizeable void left by the exit of Naby Keita to Liverpool, the Mali international is yet to find his feet after a debut season derailed by injury. He's fit again now, and could be a valuable addition to United's midfield engine room. (Photo by RONNY HARTMANN/AFP via Getty Images) Photo: RONNY HARTMANN
8. Larry Kayode - Shakhtar Donetsk
The Nigeria international has been farmed out on loan to the Turkish Super Lig where he's been on fire, and could look for a Premier League return after never getting a game for Man City during his brief spell in England. (Photo credit: JOE KLAMAR/AFP via Getty Images) Photo: JOE KLAMAR
