#3 Goals, goals and more goals
As aforementioned, Herrera was seen in vacant channels. Given his position and the fact that the Bluebirds stood deep and compact, the 29-year-old enjoyed more time on the ball. Consequentially, he was found free 25 yards out. He then launched his shot that took a vicious deflection and landed in goal, leaving Etheridge with no chance whatsoever.
Ten minutes later, out of absolutely nowhere, Cardiff won a penalty. Prior to that, Warnock's men were struggling to keep pace with a buzzing United midfield. The only way they looked like disturbing a rather solid back line was through set-pieces.
In a similar situation, Rashford handled the ball while trying to control it. The assistant had a clear view of it, which only meant that Cardiff were back in business. Victor Camarasa stood in front of compatriot de Gea and smashed a thunderous penalty past him.
Just when you thought Manchester United looked lively but not sharp enough, Anthony Martial, Pogba and Rashford interchanged pin-point passes that left everyone's jaw on the floor. Pin-point passing, quick thinking and precision had been the DNA of United's attacks over the decades, and Martial finally showed us a replay of that with a sublime goal.
