I disagree it doesn't keep it interesting at all it's annoying and somewhat ruins the game slightly.
It's not fun to play matches with un-fit players or have decent players injured due to a badly timed friendly. And the fatigue from a friendly may not be much but if your players are very low before the match and you do not have time to rest them properly after etc. then you can be *beeped* for the next match!
Thanks for the other replieshopefully they may consider changing it.
