Zonal marking on the set-pieces. It just seems counter-intuitive for any defender. Zonal marking in general play is one thing but for set pieces, with all those bodies crowding the box, it's so much more unpredictable. I don't understand how you can construct a system where players know when to zone on/off opponents among the chaos of a set piece.
The only good reason Sarri gave for it in his press conference was to avoid penalties from VAR. Pretty thin if you ask me.
Wasn't a bad performance at all in that we didn't concede clear cut chances from open play and we manage to create some ourselves. Counter-attacking goals and chances wasn't what I was expecting from this new Sarri side, especially against Atletico. When we do have the ball for long periods in our half, we don't look any chance of scoring. That's where Matuidi and especially Khedira let us down. To carve out some space from an 8, 9 man defense you need midfielders with a lot more polish and imagination.
