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...
1. Zeki Celik - Lille
The rapid right-back has been capped on ten occasions for Turkey, and could offer George Baldock some competition for his starting spot. He's also a mean tackler, and was on Spurs' radar last month. (Photo by PATRICK HERTZOG/AFP via Getty Images) Photo: PATRICK HERTZOG
2. Casper de Norre - KRC Genk
Double raid? Stranger things have happened. The Belgium U21 ace can play as wing-back on either side, and can also do a job in midfield. Lazio were after him last summer, and he's a talent of the rise. (Photo by YORICK JANSENS/BELGA MAG/AFP via Getty Images) Photo: YORICK JANSENS
3. Dominik Livakovic - Dinamo Zagreb
If Dean Henderson doesn't return to Bramall Lane next season, the Blades will need a quality replacement. Livakovic is now Croatia's number one, and will be looking to push himself to secure a move away from his domestic top tier. (Photo credit: ANTHONY DEVLIN/AFP via Getty Images) Photo: ANTHONY DEVLIN
4. Robin Gosens - Atalanta
The Serie A side boast a tactical set-up strikingly similar to United's, and the German left wing-back could adapt with ease to Chris Wilder's style of play. He's a man in demand, however, with Chelsea on his tail. (Photo by Valerio Pennicino/Getty Images) Photo: Valerio Pennicino
