Youtube lets you set the playback speed. Slow down to 0.25X under Settings (the gear wheel symbol below) and check out the screen that Powder eat for the Guatemala goal. All the defensive heads on the board - how you defend against this?
You have to anticipate that they can set a screen, players do this reguarly on corners and set pieces. I'm sure this is not the first time Powder or our players has experienced this at his level. I give Guatemala credit because they executed it well but when defending you and your teammates have to be on the same page/communicate that if one player gets screened and is obstructed, the other teammate go with the player and the one who was screened take the player he was marking. If not the open player who came off the screen will always be open to attack those balls.
Another way to defend it is through zonal marking where the players are responsible for certain spaces, since they're not man marking it's harder to set a screen....but that could cause problems if the lacks chemistry as it could lead to uncertainty and players assuming the other teammate would've cleared that ball.
But yea, I noticed that's what happened to Powder on the goal last night but by the time he recovered it was too late.
