Following him is Andrej Ilic from Union Berlin, whose performance has dropped significantly, with only two goals scored against an xG of -7.05. Other notable players include David Brooks from Bournemouth, who leads the Premier League with a -4.65 xG gap, and Issa Soumare of Le Havre, who has a -5.13 underperformance. Romulo of RB Leipzig has also struggled, underperforming by -5.15 despite a decent season overall. These players exemplify the challenges of converting chances into goals in modern football.
