Hahaha you spend about 5 minutes per match so 10 minutes in total. It's not the matches that consume time.
You now need to train aggressively for training bonuses then you need to restore condition to every player you use so that's a lot of videos to watch just for green packs. Then you need to watch videos for blue packs for morale. If you counter formations you need to do your research to beat tough opponents. If you like training you train a good player often which requires more videos.
Basically, I spend most of my time watching the Limitless trailer![]()
