When Ralf Rangnick added Sascha Lense to his coaching staff in early December he was effusive about the benefits the relatively unknown German could bring.
Lense arrived as a sports psychologist but is often on the training pitches at Carrington and was appointed as part of Rangnick's coaching staff, a distinction made explicit on his arrival.
The duo worked together at Schalke and RB Leipzig and Rangnick knew the value that Lense could add as he sought to imprint his own ideals on the Manchester United players in a shorter timeframe than he would usually get.
