Have had a quick shifty and can't see this mentioned by anyone else so, at the risk of making myself look a fool ...
In fifa 18 I must have taken around 100 pro club penalties and very rarely missed the target.
I never use much power, if you roll it into the corner it's rare that the keeper will save it.
Which brings me to the point : FIFA 19. I've taken 6 pens so far. 5 of them are still on their way to the Orion nebula and the sixth managed to find its own way into the net off the underside of the bar.
Something is definitely amiss and I'll tell you how I know...
If I take a pen in career mode everything is 'A ok'.
If I take pens in career mode training exercises, no problems.
ONLY Pro Clubs ... and I'm not the only one because I've seen more Ryad Mahrez specials than usual from other players too.
PS: I've not had the first patch yet ... could that be the culprit?
