Leicester fans made their feelings known towards Harry Maguire at the weekend, but their chants backfired spectacularly just minutes into the game at Old Trafford.
Magurie was jeered by the travelling supporters when he touched the ball and a chant was directed his way.
"F*** off Maguire, we don't need you, we've got Soyuncu," they sung.
Nevertheless, just eight minutes into the game, the Turkish defender was at fault, bringing down Marcus Rashford in the penalty area.
The England striker stepped up and dispatched the spot kick coolly and the goal proved to be decisive as United returned to winning ways.
