From their recent head-to-head clashes, a stark difference in attacking efficiency is obvious between the two U21 sides.
Charlton U21 has recorded an 18% finishing conversion rate in recent matches, twice as high as Cardiff U21's mere 9%.
When it comes to key pass success rate, the home side delivers far smoother frontcourt build-up, hitting a 42% success rate that outperforms the away side's 35%.
Charlton controls the midfield with high-frequency short passes to compress the opponent's operating space, and their counter-transition speed reaches 3.2 times per minute, which effectively breaks through the opposing defensive line.
Running stats show the home side completes 27 more high-intensity sprints across the full pitch than their rivals, and their sustained heavy pressure forces the away side to make far more unforced errors.
