Expected goals models tell you how many goals a team should have scored based on the quality of their chances. Actual goals tell you what happened. The gap between the two is finishing luck, a signal that captures everything from clinical strikers to crossbar-rattling misfortune. It matters because, historically, it's one of the least sustainable edges in football. Teams that massively outperform their xG tend to regress. Teams that massively underperform it tend to improve. The ball finds a way.
This season's spread is unusually wide.
Most Cursed by Finishing
1. Crystal Palace - 35 goals from 48.8 xG (-13.8). Palace are missing by the widest margin in the league, and it's not particularly close. Nearly 14 goals have vanished between the chance creation and the back of the net. On paper, they should have a completely different season.
2. Chelsea - 53 goals from 62.4 xG (-9.4). Chelsea are generating plenty of high-value opportunities. They're just not converting them at anything close to a normal rate. A squad with this much attacking talent leaving 9.4 goals on the floor raises questions that tactics alone can't answer.
3. Leeds - 42 goals from 48.4 xG (-6.4). Leeds have been creating at a rate that suggests mid-table comfort, but their finishing has dragged them into less comfortable conversations. The 6.4-goal deficit isn't catastrophic, but it's the difference between breathing room and anxiety.
4. Wolves - 24 goals from 29.2 xG (-5.2). Wolves already struggle to create volume. When you generate only 29.2 xG worth of chances all season and convert just 24 goals from them, margins get very thin very fast.
5. Brentford - 48 goals from 52.8 xG (-4.8). Brentford's gap is the mildest on this list, but 4.8 goals still represents roughly two wins that slipped through their fingers.
Most Blessed by Finishing
1. Tottenham - 42 goals from 34.7 xG (+7.3). Spurs are outscoring their expected goals by the largest margin in the league. Whether that's clinical finishing or fortunate bounces is the question that will answer itself over the remaining fixtures.
2. Manchester City - 65 goals from 58.4 xG (+6.6). City's 6.6-goal surplus feels almost modest by their standards. When your squad features this caliber of finisher, some overperformance is structural. Some of it isn't.
3. Arsenal - 63 goals from 56.6 xG (+6.4). Arsenal's numbers mirror City's almost exactly. They are creating at an elite level and finishing above it, a combination that wins titles when it holds and causes cold sweats when it doesn't.
4. Burnley - 34 goals from 28.4 xG (+5.6). The most interesting name on the blessed list. Burnley are not a team you'd associate with clinical overperformance, yet here they sit, 5.6 goals to the good. If regression comes calling, it could get uncomfortable.
5. Aston Villa - 47 goals from 41.7 xG (+5.3). Villa have been quietly efficient all season, extracting 5.3 more goals than their chances suggested. Ollie Watkins tends to make these numbers feel deserved until the sample says otherwise.
What This Tells Us
The range this season runs from Crystal Palace at -13.8 to Tottenham at +7.3, a spread of over 21 goals driven by finishing variance alone. That's enormous. Historically, finishing luck is among the most mean-reverting signals in the Premier League. Teams that overperform their xG by more than four or five goals tend to see their conversion rates normalize the following season. Teams that underperform by similar margins tend to bounce back.
Palace's deficit is large enough that regression alone could swing their goal total by double digits next year. Tottenham's surplus, while partly explainable by individual quality, is steep enough to warrant caution.
The xG model doesn't care about narratives. It just counts the chances and waits.
