3 things that went wrong for Manchester United against Chelsea

#2 Playing too narrow

Lukaku's injury was a big blow

Rashford started up front for United and was flanked by Sanchez and Lingard and the trio often interchanged positions at will throughout the match.

Both Sanchez and Lingard like to cut inside and play at close quarters and the Chelsea defenders had their work cut to a large extent as they could easily outnumber any United player inside the box.

Conte set his team out in a 5-3-2 formation when not having the ball as he always does and the United players were rarely given spaces in the inside channels to take advantage of. They were closed down quickly by one defender or the other and their only natural width came from the full backs who failed to put in decent deliveries.

They also lacked any runners behind the Chelsea defensive line and thus they could stay compact and solid instead of being feared of getting stretched out.
