Ralf Rangnick watched on as Manchester United's Under-19 crashed out of the UEFA Youth League at the hands of Borussia Dortmund in controversial fashion.
The Red Devils youngsters were beaten on penalties after the match a back-and-forth 90 minutes saw the scores at 2-2 in the youth equivalent of the Champions League.
Former Manchester City academy prospect Jamie Bynoe-Gittens scored both of Dortmund's goals and bagged the winning spot-kick in the shootout.
