I had an impression that we stopped pressing after Mo went off and didn't start again until after the third goal. It was just a vague impression and my short term memory ain't what it used to be, so I watched a coupla highlights reels, which didn't show the build-ups from the back. However, both extended highlights I watched showed the same thing: it's nearly all us up to Mo going off, with Real only having three attacks: the one Karius punched out, Marcelo's scuff wide and Ronaldo's near post miss. They were making mistakes all over the place.
As soon as Mo goes off, it all reverses. It stays that way until the third goal, which was when the highlights end but it seemed like Real sat back then and our pressing just looked desperate, without any highlights.
