The Red Devils took a 2-0 lead before a Foxes goal in response was met with a second half third from LVG’s men courtesy of Ander Herrera.
But a penalty scored by David Nugent, an Esteban Cambiasso effort, a goal from Jamie Vardy and a second spot kick, converted by Leonardo Ulloa, saw United slip to a shock loss at the hands of the newly promoted side.
The result was the latest in a disappointing start to the season for the Old Trafford outfit, and Van Gaal was frustrated after the final whistle:
“How is it possible to give this game away? We have given the game away,” he is quoted by ESPN.
“Leicester has proven already in four games that they have a strong character and that when they are 3-1 down, you can play all the game with more possession but you cannot do these kinds of things [mistakes].”
United had taken the lead through Robin van Persie before newbie Angel di Maria netted with a delightful chip.
Ulloa scored in response, with his second – Leicester’s fifth – his fifth goal of the season so far.
