TLDR
There's no defensive structure. Defending remains individual without a clear line or system. Players aren't talking to each other to play an offside trap or help each other out. Players aren't working hard enough to press the ball or to track back when we lose it. That leads to individuals playing the opposition onside, or allowing them to get the ball in the box, or making errors that lead to goals.
The long story.
I would really suggest people go and watch the "highlights" of the game before slagging this kid off.
There are so many issues with our defending. The first could have been avoided. It's a tricky ball in the air and he makes the wrong decision, so does Gvardiol. But it's 3-1 and you're still in the driving seat.
Look at our defending for their second goal. They have three players in the box, we have 6. There's no pressure on the ball so it's easy to get the ball in. There's no defensive line. If Gvardiol steps up their players are offside. There's an overlapping player out of shot, that Nunes hasn't picked up either. It's a shambles.
And here's the third goal. Lewis playing the runner on side. No confidence or leadership on keeping the defensive line and playing offside. No defensive structure or shape, everyone loaded up on the near side.
Feyenoord have four players bursting into space and Lewis is now the only player in a position to get back.
But now look at the next frame. Where the hell is the urgency to get back?
If you look at Bernardo from the 1st image to the 2nd he's barely moved.
Then you look at the final image below, and it shows that when he finally put his foot down he was too late. If a few of our players had have instantly put their foot down and tried to get into position we might have been able to deal with the situation.
