If you watch the way other teams press you'll often see them 'activate' to certain triggers such as a lofted horizontal ball in the back half. You'll also see them guide a teams build up play through their pressing. For example, a player may come at the goalkeeper from his right side in order to get him to pass to the right back who is uncomfortable in possession. This is an example from a couple of seasons ago. Atletico did something similar against Barcelona in the QF and completely shattered Busquets in the 1st of the 2nd leg. I swear our midfielders just run at the opposition CB because they feel compelled to do something.
