Pressing
Pressures on the ball determine how willing a player is to press his opponent, and while some of this is dependent on the style of play of the team they are playing for, it does show you how prepared they are to harry the opposition.
Digne is more willing to press (14.3 pressures per 90) than Emerson (10.7 per 90) based on the statistics we have available. With Tuchel keen on players who work hard off the ball, Digne has it in his game to meet expectations.
