I'm no expert on tactics, but there were many occasions in that game tonight where Amorim had a flat back five. And they were marking nobody, because Leicester were all in their own half, so you had 10 Leicester players against 5.
Even with my rudimentary skillset, I know that 5 players are not going to overcome 10. Which is why they can't even muster a shot on goal. They can't even get the ball into the penalty area, because the opposition will snuff out any attempts to play it down the channels, and they will outnumber in midfield. Every time Mainoo received the ball, he had 3 Leicester players tackling him. This is really basic stuff, but it doesn't seem like the penny is dropping.
It is like watching a weird experiment, but the bunsen burner has set fire to the curtains, and the roof is on fire.
"Amorim? Not for me, Geoff."
