I tried some training today, teaching Aerial Defense SA to a newly bought DC-DL. He got 5/50 while spending 4 green packs.

Same for my reserve GK, He's about to level up, I spent 6 green packs and he got from 63.6-65.6 to 63.8-65-8, while doing solo training (I didn' care about the bonus), mainly physical and goalkeeper training.

Please be aware that also if you don't get any notification of gain during training, you are actually gaining some small amount. In 2 different drills I didn't get any notification, despite noticing a 0.1 point gain in the skills tab.

I still think we need a progress bar for an easier check, but I don't think it's bad. It needs some practice and of course more tweaks from Nordeus.
