Deer in the headlights defending?

Otherwise, I'm not sure that I understand the reference...

Arnold was a surprise start for Liverpool. He's a RB. So attacking him with speed and power from left wing seemed a logical choice (i.e. Martial). But it wasn't working.

Then Mou (who I hate with a passion), made a pretty genius tactical move. The world had to laugh when Fellaini came in. But they used him to knock down the long ball and bring pressure from the left and middle.

Imagine that you are 18 years old and you see Mkhitaryan running at you with Mata and Rooney ready to feed Ibra. I'm not sure how many players would have been ready for that plan, let alone an 18 y/o. That D-bag is a hell of a tactician.
