Chelsea 0-2 Manchester United: 5 Talking Points
First-half goals from Ander Herrera and Paul Pogba sealed the visitors' progression into the quarter-finals, where they will travel to fellow Premier League side Wolves next month.
The manner of this latest defeat, coupled with puzzling tactical decisions and a poor collective performance has left many supporters calling for Maurizio Sarri to be sacked in west London.
It's their fifth defeat across all competitions in 2019 and their inconsistent form doesn't seem to be changing anytime soon: a Carabao Cup final against Manchester City, followed by a London derby against Tottenham next week awaits the Blues. With all of that in mind, here's a look at five talking points from United's latest win:
#5 Hazard and Higuain focus as Chelsea falter again
In a frustrating encounter where Chelsea dominated possession but had no goals to show for it, they lacked penetration and a real cutting edge - something that has been said for a while now. Even still, it didn't stop Gonzalo Higuain and Eden Hazard in particular from trying as the hosts created half-chances and probed in bursts over the 90 minutes.
In the first half, Higuain missed two chances in quick succession. The first was a sign of hesitation before fluffing his lines as Sergio Romero rushed out to smother the danger, watching the ball fly over the crossbar. Just minutes later, he headed wide of the far post from distance.
As far as Hazard was concerned, his Chelsea teammates couldn't cope with the rapid intensity changes and the Belgian was left shackled by poor service when it really mattered.
Huffing and puffing his way towards the box with his usual slaloming dribbles, it was easier than it should have been for the returning Chris Smalling and others to isolate him. They could sense his urgency and looked to double up on him quickly, to reduce his effect while regularly dispossessing him. Unfazed, he still managed to complete a game-high eight dribbles, but the hosts lacked the finishing touch to recover in a tie they could've won.
Executing the intricacies well - neat flicks and deft touches - but you could sense he was getting increasingly frustrated as time wore on. His excellent passes into Higuain went without reward, with the Argentine clearly still not at 100%, while neither Pedro nor Willian could match his levels.
