Set Piece xG
A Ballity concept guide — learn what it is, then spot it live.
What Is It?
Set Piece xG (Expected Goals) quantifies the quality of scoring chances created directly from dead-ball situations like corners and free-kicks, indicating how likely a shot taken from a set piece is to result in a goal.
In Simple Terms
It tells you how good a scoring chance from a corner or free-kick actually was, before the shot is even taken.
Why Top Teams Use It
Top teams use Set Piece xG to refine their attacking and defensive set piece strategies, identifying the most effective routines and assessing players who consistently generate high-quality scoring opportunities from dead balls.
Two Ways to See It
Data Lens
From a Data Lens, analysts track Set Piece xG values for individual routines, delivery types, and targeted players to quantify the actual danger posed by dead balls. This helps objectively evaluate the effectiveness of different strategies and personnel.
Scout Lens
A Scout Lens observes the qualitative aspects: how defenders are positioned, the precision of the delivery, and the attacker's movement to create space or connect with the ball. They identify why certain set pieces feel more threatening, correlating with what Set Piece xG later quantifies.
Example Teams / Players
many teams across modern football, Liverpool (under Klopp), Arsenal (under Arteta)
Spot It During a Match
During a match, watch for how well a set piece delivery creates a clear, unobstructed shot attempt from a dangerous area, particularly from a player known for good finishing.
