#6 Daley Blind (Manchester United)

Daley Blind has strongly been linked with a move away from Manchester United in the January transfer window. Having been used sparingly by Jose Mourinho this season, the United defender has reportedly been courted by the likes of Barcelona.
In fact, according to ESPN (via The Metro), the Dutch international will be allowed to leave by Jose Mourinho if he does indeed demand a transfer.
The 27-year-old has made only 3 Premier League starts this season with Mourinho preferring Ashley Young to play in the left-back position. Although Blind did start the FA Cup tie against Derby County, he still remains behind Phil Jones, Eric Bailly, Chris Smalling, Victor Lindelof and Marcos Rojo in the pecking order.
Capable of playing in multiple positions (left-back, centre-back, and even as a central defensive midfielder), Blind can certainly prove to be a useful squad player for any team in Europe. With the Dutch international's contract running out next year, United might well cash in on the defender in the January transfer window.
