I simply do not understand how someone could possibly compare Lingard to Memphis, Adnan, Pereira, or even Young. All of these players actually showed flashes of brilliance before they were mired in Van Gal's swamp of non-existent movement and overpassing.
Lingard has only shown no identifiable skill, no ability to cross, no dribbling skills, tremendously poor finishing and almost zero potential. Not even Pep or Mourinho could possibly save him. same goes for McNair, Blackett, BJ, Phil Jones, Rojo, Fellaini, Romero...
