Paul Pogba scored an early goal from the penalty spot and Luke Shaw got his first career goal before James Vardy pulled one back for the foxes.
After just few minutes into the game, Leicester defender, Amartey handled the ball in the box which gave way for a penalty. Paul Pogba took his time in the run up to the spot kick before slotting it above Schmeichel's head into the net.
United looked good from the start even though they were notable players missing from the starting eleven with the likes of Lukaku, Young and Vardy starting from the bench.
Luke Shaw scored his first professional goal when Mata gave him a past that he slotted in the net, though he was a little shaky.
