If the pressure is to intense, and you can't drop further back to allow yourself more time, you need to go long a few times. We tried, but not long enough in the first half. We went semi-long, and then lost the duel. By precisely putting a few long balls in behind the opposition defence, with quick players threatening, you not only have the potential to create a break, but you force the defenders to turn and run facing their own goal. A few of those, and they will inevitably start to drop of a bit earlier, thus creating more space in central midfield.
