Seems like Mourinho's basic plan is to allow teams to come forwards and press in our half.
So that we can spring sudden counter-attacks with pace.
This is something I've advocated for a while, when watching AVB and Poch just passing back and forth, back and forth.
Sometimes it is fruitful to lure a team in, then hit them on the break.
It also means your defence is more "set" rather than chasing backwards out of position.
Of course with Son out, this gives us another dimension to play 1 or 2 or 3 of Lo Celso, Ndombele, Gedson, so the big issue is whether Bergwijn/Moura can score on the break. They look like they could.
