It's not known as the world game for no reason.
On Wednesday morning (AEST), three explosions occurred near Borussia Dortmund's team bus as they were about to depart for their UEFA Champions League clash at home against Monaco.
Dortmund defender Marc Bartra suffered a broken wrist following the explosions and underwent surgery almost immediately.
Windows in the club's bus were shattered with Bartra suffering cuts to his face and arms as he was the only person injured in the incident.
In an amazing show of solidarity between fans, the travelling AS Monaco chanted "Dortmund, Dortmund" as news filtered through the stadium that the match had been postponed.
Borussia Dortmund's official Twitter account started the hashtag #bedforawayfans with many photos emerging across social media of fans of both teams sharing meals together at residents of home fans.
