Jabulani - The Greatest Shambles in the History of Football

The Football World Cup - the biggest sporting event on planet Earth.

And for it they design the worst football imaginable.

Ive never seen so many mis-hit passes or shots fly 10 yards over the bar. The only three goals scored outside of the box so far in the WHOLE tournament have been from keeping errors and a deflection from Forlan's last night.

It is embarrassing and IMO almost solely responsible for the diabolically bland tournament so far.

A sh*tload of heads should role over this joke.

I agree Tommy

interesting to read in that article that Addidas are saying its not lighter at all, its the fact that they are playing at altitude

I have not seen anything that tells me the difference between the jabulani and the conventional balls

is this just a marketing ploy by Addidas to sell more gear ?

Everyone is blaming the ball, but what they are saying the ball does is what happens at altitude

There is definitely is a problem with the weight of the ball..... Can't remember a tournament where I've seen the ball fly over the bar more

I think it's something to do with the dimpling on parts of the ball. It seems really hard for the players to hit long passes in the air and it looks like it flies further than it should sometimes. Has there been dimpling on balls before?

if it does have dimples it will be more aerodynamic, thats why gold balls have dimples and why a cricket balls swings reverse when its gets older and peices taken out of it, sort of like dimples

no matter how hard I look, I dont see any dimples

As for games being at altitude, theyve only known about it for 6 years.

I played a game last night with one of these balls. I coped fine. If someone of my limited talents can shoot straight i'm sure the experts should be able to. Its round, about as heavy as a normal ball and bouncers like any new ball. In fact it is just like a new football. Nothing more, nothing less.

It gave me a good excuse for the stream of bad passes and misses though, which was nice. ;-)

Yeah seems much more like an altitude problem.


Look at Germany. Smashes us at sea level, destroyed by Serbia at altitude

this is a good read

no mention of dimples though


They call them 'aerogrooves' but it's the same principle as golf ball dimples. They break up the air as it goes over the ball and the low pressure 'balloon' behind the ball is smaller, reducing drag and making it fly further. I don't know if that is making it harder for the keepers but the ball shouldn't drop as much in flight, but a lot of the long passes seem to be overhit and I think the ball would have something to do with that.



This coefficient of drag is what is being altered by the new ball. The fewer panels, rounder shape and aero grooves all have an effect. The fewer panels and rounder ball allow the striker to get more of the ball in his shot and also control the rotation on the ball. This should result in higher ball speeds off the players boot and cut the initial drag. The increased rotation creates the effect of moving air on one side of the ball faster than on the other, creating a force which makes the ball swerve more. The aero grooves produce turbulent flow around the ball (similar to the grooves on a golf ball) allowing it to also cut down on drag and fly through the air faster and further.

Uruguay v Ghana was Jabulani 1 v Jabulani 1, wasn't it?

Muntari's goal from about 1000 miles out was a decent strike at best, which travelled straight 90% of the way and then went left to right at the last second. Forlan hit his strike with the inside of his right boot, and yet it randomly went left to right at the last second? wtf?
