3. Stefan de Vrij
While de Vrij’s current form in Italy has barely been inspiring, he could well be an upgrade on United’s fragile defence. Blackett is due a mistake every game, thanks to his positional naiveness, while Jonny Evans and Phil Jones are fond of the treatment table. Chris Smalling’s inclusion barely inspires confidence, while Rojo at centre back is hardly assuring. De Vrij has struggled to adapt to life in Italy after Lazio snapped him up after the World Cup, and has failed to make an impression. Does van Gaal want to make a January swoop for a player he has worked with before and knows what he’s all about? Unlikely, but possible if United failed to land Hummels or Vlaar.
