Someone that works on weekends & gets, for example, a Monday off, will be more than happy, don't you think? Probably a minority but still. If you want to watch a game live, away from home, you'd have to live with the consequences. Applies for many of the supporters from Bayern or Dortmund, who regularly fly out to support their teams in Europe - during the week.
Frankfurt v Leipzig as well as Dortmund v Augsburg are played on a Monday EXACTLY BECAUSE OF scheduling issues & it helps the teams. I'd be mad if it becomes the norm, but if it is done to help teams have longer breaks after their European ties, then so be it. There was uproar last season, iIrc, because, (was it Schalke?) the had to play 48 hours after their European game?
EDIT; It was Freiburg. 55 hours between two games because of scheduling difficulties due to the 2. Bundesliga, midweek matches and, of course, the Europa League.
