What happened, was that Dier and Sanchez, who were getting praised, started doing what they do. Add in the usual 89th minute Aurier brain farts on the edge of the box and suddenly any thought of attack was held back with "we need bodies to back these goons up"
And here we are, another year later, the same 2 CBs involved in a clean sheet and getting praised.
Except City had their fair share of chances that better CBs would have cut out fairly easily.
You won't see it on match or the day, but a glaring lapse of concentration from Dier in the first half saw a simple sideway pass across the front of him completely missed. He didn't even seem aware of it. Luckily for us and him, City frittered the chance away.
2nd half, Sanchez loses Grealish who blasts straight at Lloris. Another day and those 2 errors are goals and people are calling out the defence.
