3 Reasons why Chelsea lost 2-0 to Manchester United | FA Cup 2018-19

#1 Major miscommunication at the back

Another horrible day at the office for Marcos Alonso

The hosts weren't all that bad defensively, but only with regard to a few aspects. They pressed high up the pitch and portrayed some decent energy in the opposition third and in the middle, but at the back, Chelsea appeared clueless and to be honest, reluctant.

Take nothing away from Herrera and Pogba, who planted fabulous headers past Kepa Arrizabalaga. But for the first goal, no midfielder got close to Pogba, as he had all the time in the world to pick out Herrera.

The Spaniard, who was initially being marked by Marcos Alonso, was left free due to miscommunication between David Luiz and the left back.

And, you know what happened next.

For the second goal, Rashford got to the right flank with ease, as though he were in front of practice cones. He delivered a fine cross into the box, but Pogba, with aplomb, got in front of Azpilicueta, whose legs were pinned to the ground. Poor, poor defending!
