The Bundesliga, Germany's top football league, has seen a dismal performance from many of its teams in terms of goal difference. A staggering 66.6% of the teams have a negative goal difference, indicating that more than two-thirds of them are struggling to score or concede goals.
In comparison, the English Premier League fared slightly better, with only 14 out of 20 teams finishing with a negative goal difference in two seasons, albeit still a significant majority. The record for the highest percentage of negative goal differences is held by Division Three South in the 1952-53 season, where an astonishing 75% of teams were struggling to score or concede goals.
In Portugal's top flight, a similar trend can be seen, with only four out of 18 teams finishing with a positive goal difference. The same pattern was observed in the 2017-18 and 2009-10 seasons, with Benfica, Porto, Braga, and Sporting being the only teams to buck the trend.
The lowest percentage of teams with a positive goal difference is attributed to the 1990-91 season in Portugal, where only 20% of the 20 teams managed to score more goals than they conceded. This is likely due to the dominant performances of Benfica and Porto, who between them scored an impressive +128 goals.
In European football, other leagues have also seen a high percentage of negative goal differences. In Romania's Divizia A in 1988-89, only four out of 18 teams finished with a positive goal difference, although one team had a neutral goal difference due to the fact that they scored and conceded an equal number of goals.
The question also raises interesting connections between managers and their sons, with two instances of fathers and sons playing for different teams in the same league. However, another example of fathers and sons playing for the same team is less frequent, and only one instance was found to date.
Finally, several questions were submitted regarding record wins and losses, locations named after football clubs, managerial sackings, and unusual culinary crests on football club badges, but these will have to wait for a future edition.

I'm tellin' ya, the state of football nowadays is just crazy! 
I mean, 66.6% of teams in the Bundesliga can't even score or concede goals? That's like me tryna cook a meal with no ingredients 
. And don't even get me started on the English Premier League, it's like they're all strugglin' to find their rhythm 
. I'm not surprised though, 'cause back in my day (aha!), we used to say that football was about defense, not offense 
. These youngbloods today are more worried 'bout scorenin' goals than keepin' the other team from scorin' 
! Give me a break, kids! 
. It seems like many of them are struggling to find their footing, and it might be a sign that they need to re-evaluate their strategies or make some changes in their coaching staff. Comparing it to other leagues, the English Premier League is doing slightly better, but still, 14 out of 20 teams having negative goal differences is not something to brag about 
.
. However, I'd love to see more examples and analysis on this topic in future editions.
. Portugal's top flight seems to be struggling with it, especially since Benfica and Porto dominated the league back then 
. What can they learn from other successful leagues?
meanwhile england is like a contrast to that with only 14 out of 20 teams having negative goal diff it's still pretty sad tho 
and did u know about portugal's top flight too? it's like they're all struggling to score or concede goals 
I mean, I knew it was tough for them, but that high percentage is crazy! The fact that more than two-thirds of those teams are having trouble scoring or conceding goals is just wild. Meanwhile, the English Premier League doesn't do much better with only 14 out of 20 teams still in the red.
Are they just not good enough or something? 
and btw, did you guys know that Benfica and Porto dominated Portugal's top flight for years with their +128 goals scored vs conceded? 
that's insane!
. and it's not just them, Portugal's top flight is also struggling 
. I mean, what's going on in those leagues? 
๏ธ. anyway, can't wait to see how the rest of the season goes 
.
. The Premier League and Portuguese league aren't much better, though - it seems like a lot of teams in Europe are just not clicking on all cylinders right now.
. I'm curious to see if anyone can break their streak this season. Maybe some new blood will come in and shake things up?
Portugal's top flight isn't doing much better only 4 teams managed a positive goal diff 
. Can't help but wonder if they were just having an off-season or something... 
. Anyway, it'll be interesting to see how things play out for the rest of the season 
. The English Premier League isn't doing much better either, 70% of teams losing goals 
I think it's cool when they play for different teams, but sometimes it's just weird 
but hey at least benfica and porto were able to pull off some impressive performances back in the day
