Manchester United have had to make a few unorthodox selections this season due to their injury crisis, but none of the surprises Erik ten Hag has pulled this season can rival fielding 19-year-old Willy Kambwala away to West Ham on December 23.
Kambwala was so obscure that his name could not be found on the matchday programme at the London Stadium. He had only once before been named in the matchday squad, the previous week at Anfield, and wasn't part of United's main group on their pre-season tour to the United States, while many other youngsters featured.
So who is the defender that Ten Hag has thrown into the deep end? GOAL has all you need to know...
