When Bad Luck Becomes a Plague: La Liga on Matchday 17

Misfortune has a name – and Athletic Club wears it

Sometimes football is just plain cruel. A team dominates for 90 minutes, creates chance after chance, and still ends up empty-handed. Matchday 17 in La Liga was a prime example of how Expected Goals and actual results can tell two completely different stories. While some teams could celebrate undeserved points, others had to learn the painful lesson that football is sometimes simply unfair.

Match of the Week: When Quality Meets Luck

At the Estadio Manuel Martínez Valero, spectators witnessed a statistical oddity of the special kind. Elche CF defeated Rayo Vallecano 4-0 – even though the guests from Madrid showed slightly more quality with 2.0 xG than the hosts (1.85 xG). A result that looks completely crazy on paper, but once again proves in reality: efficiency beats Expected Goals.

Rayo Vallecano must be wondering what they actually did wrong after this match. The answer is simple: Nothing – except missing their chances and allowing their opponents to capitalize on every opportunity. Elche, on the other hand, showed pure clinical finishing and converted practically every halfway dangerous moment into a goal. That's how football goes sometimes, even if the xG models shake their heads in disbelief.

Lucky Winner of the Matchday: Triple Jackpot for the Surprise Teams

Three teams can consider themselves winners blessed by lady luck. RCD Espanyol, Real Betis, and Elche CF each grabbed three points despite their Expected Points only sitting at a measly one point. A delta of +2 points – that's quite remarkable.

Particularly spicy: RCD Espanyol won at San Mamés Barria against Athletic Club 2-1, even though the Basques showed significantly more quality with 2.03 xG than the Catalans (1.2 xG). Sometimes a little extra luck is enough – and a goalkeeper who defends his goal like Fort Knox.

xG Victims: Athletic Club and the Law of Great Injustice

If bad luck had a club, it would probably be called Athletic Club. 2.03 xG against only 1.2 for the opponent, and still lost? That's the football equivalent of a lottery ticket with five correct numbers that still wins nothing. With -2.5 in the matchday delta, the Basques were the biggest unlucky souls of the matchday.

Looking at the entire season, the picture becomes even more dramatic: Athletic Club sits in 8th place in the official table, but with 45 Expected Points should actually be in 4th place – right behind the top 3. Eleven points difference between reality and performance, that's quite considerable. The fans at San Mamés Barria can only hope that luck will eventually turn.

Honest Table Position: When the Truth Hurts

At the top, there's surprising honesty: Both FC Barcelona and Real Madrid lead both tables, although both teams are running 6.5 and 7.5 points above their xP values respectively. The real surprise, however, is hiding in 3rd place of the official table.

Villarreal CF is the absolute lucky charm of the league with 23.5 points above their xP value. 51 points with only 27.5 Expected Points – that's a ratio that would amaze even die-hard statistics skeptics. In the honest xP table, Villarreal CF would only be in 13th place, but in reality they're fighting for international spots. Chapeau!

The biggest sufferers, alongside Athletic Club, are also Real Sociedad (-4 points) and surprisingly Rayo Vallecano (-4.5 points), who would actually be in 9th place in the xP table instead of their current 15th position.

Outlook: Luck is a Fickle Thing

The next matchdays will show whether this season's statistical anomalies slowly balance out. Villarreal CF should mathematically face tough times ahead – 23.5 points of luck advantage is unusually high even by Spanish standards. Athletic Club, on the other hand, can basically only get better – statistically, it can hardly get worse.

For FC Barcelona and Real Madrid, the rule is: leading both tables is never wrong, even though both teams probably know that their performances alone might not be enough for the title. In a league where luck and bad luck are as unevenly distributed as they currently are, anything can happen. That's also part of football's fascination – sometimes it's not the better team that wins, but the luckier one.
