Well, no one saw that result coming.
Manchester United travelled to Chelsea on Sunday on the back of a goalless draw with Liverpool and a 4-1 thumping against Fenerbahce in the Europa League.
Spirits were high and it seemed Jose Mourinho's men were finally on the mend following a poor run of form that saw five points won out of a possible 15 in the Premier League.

And yet, against Antonio Conte's Blues, United were once again awful and slumped to a rather embarrassing 4-0 defeat.
The likes of Zlatan Ibrahimovic and Paul Pogba have been blamed in the aftermath, but video replays show that one player was at fault for every one of Chelsea's goals at Stamford Bridge: Chris Smalling.

In what was an abysmal performance from the stand-in captain, he made a number of basic defensive errors that cost his side dearly (see below).
Smalling, David de Gea and Daley Blind were all to blame for Pedro's opener, but a distinct lack of communication and naivety from the England international allowed Chelsea's winger to race in behind and finish.
He should have just cleared his lines.
For the second, Smalling failed to track his runner and allowed Cahill space to fire home when the ball fortunately landed at his feet from Hazard's corner.
The 26-year-old then allowed Hazard to cut inside on his stronger foot far too easily for the third goal and made a pathetic attempt at stopping Kante's advances for the fourth.
Overall, it was a disastrous performance from Smalling, who was deservedly awarded a 0/10 from Manchester Evening News for his contribution at the Bridge.
And to think, it was only last week the centre-back suggested United can challenge for the Premier League title this season following the draw at Liverpool.
"I think we have got more than enough," he said, per the Guardian. "I think we have shown we can score goals and on nights like this, we can keep a clean sheet and not give too many chances to them.
"We can do both sides of the job and it is about consistency now. We need to go on a little run and show people we are a team that is a threat.
"I think the fixtures we have got this week are ones that we can make a turning point this season. We have got a clean sheet which has not happened for a few games.
"Hopefully we can kick on now, we have got Thursday and Sunday, and confidence is good."
