Manchester United's early season problems were compounded by a humiliating 4-0 loss to third-tier Milton Keynes Dons in the League Cup second round on Tuesday leaving new manager Louis van Gaal still looking for his first win.
MK Dons' Will Grigg and substitute Benik Afobe scored two goals apiece as United's defensive frailties were ruthlessly exposed by their enthusiastic lower division opponents who took advantage of playing against a second-string side.
Grigg capitalised on United's mistakes to score either side of halftime before Afobe compounded the visitors' misery with two late goals, the first seconds after coming off the bench.
It was United's first outing in the second round of the competition since 1995 and the first time they had conceded four goals in a League Cup match against lower league opposition.
Following Manchester United's 2-1 Premier League defeat by Swansea City, their first opening day loss at home since 1972, and a toothless 1-1 draw at Sunderland, they should have welcomed a seemingly straightforward game at lowly opponents.
After a bright start, though, they found themselves behind.
Just after the hour mark the hosts doubled their lead and again United were the masters of their own downfall.
Another misplaced pass was capitalised on by Ben Reeves whose cross was steered home by Grigg's audacious chested finish.
