It was clear in the West Ham game what the tactic was. We would keep the ball in our half; passing it between our defenders and midfield. We would invite West Ham to press, and when they did we would play a long ball out to the wings for our full backs to run onto.
This didn't work out since our CBs nor our midfield can play accurate long balls. All of them were over hit and way off target. Go watch a Liverpool game to see how it is done property.
Once West Ham got a goal, they no longer pressed and sat back. This gave us the opportunity to build our attacks and pass the ball. However, with all of their players behind the ball there was no room to pass it in the final 3rd. Kane's movement and appetite for the ball was non-existent; and with no space behind the back 4, Son's strengths were neutered.
The old footie tactic of 'lump it into the box and attack it' wasn't even attempted. Son, Ndombele present no aerial threat. Kane no longer attacks headers because of his ankles; which only left Moura (the shortest man on the pitch). Alli probably would have been a better option in the final 15 minutes; instructed to simply stay in the box and make a nuisance of himself.
Outside of a wonder strike from outside the box, I'm not clear what Nuno expected Bergjwin or Gil to do against 10 men behind the ball.
