Recorded crowd in lieu of roars

Broadcaster Sky is offering viewers the option of watching Bundesliga matches with recorded crowd noise, including singing, when the league resumes without spectators on Saturday.

Sky said viewers could choose to watch the matches with natural sound, which is likely to be shouts of players and coaches or opt for an "alternative audio with a recorded stadium atmosphere".

Unforuntately, the spectacle of the Rivierderby will be missed today with no flares or chants expected inside the stadium. There will certainly be no defeaning roar, either after a goal is scored or from the mouths of lions as once  was the case in a 1969 Revierderby.

Their rivalry had grown immeasurably as Dortmund rose up and took a slight upper hand after decades of being dominated.

After Visiting Schalke took the lead, a fan invasion led to police storming the field with their dogs, who ended up biting Schalke's Friedel Rausch and Gerd Neuser

Both teams met again in January 1970, and the Dortmund players found a warning when they strode onto the field -- four lions rented from a nearby safari park.
