Historic matchday in La Liga without a home win

Leganes and Osasuna brought La Liga matchday 30 to a close with a 1-1 draw on Monday night. It was a result that went down in La Liga history, as it meant that none of the 10 home teams on this matchday managed to take all three points.
It is the 4th time in the 94 editions played throughout history that no home team has managed to win. The last time this happened was in 2005-06, 19 years ago. On that occasion, there were a total of 7 draws and 3 away wins, while now there have been 3 home draws and up to 7 away wins.
Previously, in the 2002-03 season, this also happened on matchday 33 (6 draws and 4 away wins), while the first time this happened in the Spanish top flight was in the 1992-93 season.
On the other hand, Osasuna came close to taking all three points from their visit to Butarque. This would have been the 8th win for an away team in a single matchday, setting a new milestone 97 years after its birth. However, with 3 minutes remaining, Leganes equalised with a goal from Dani Raba, ending the game in a draw. It thus equalled with 7 to 4 other courses in which the same thing happened: R.37, 1995-96; R.30, 2010-11; R.4, 2014-15; and R.33, 2021-22.
In addition, La Liga matchday 30 left an unusual event, as this milestone occurred with Real Madrid and Barcelona playing, and not winning, at home, something that happens for the first time in the history of the competition. The 'Merengues' lost 1-2 against Valencia, while the 'Cules' drew 1-1 against Betis. Undoubtedly, a fact that highlights, once again, the great attraction of the league competition in Spain.
