The terrorist organization ISIS wants to start intimidating football.

According to the Spanish media, ISIS threatened that there may be "fireworks" in the quarterfinal matches of the Champions League.

So far, nothing similar has happened, as both the "Real" - "Manchester City" and "Arsenal" - "Bayern" matches passed without external scandals.

ISIS also threatens to attack the "Parc des Princes" and "Wanda Metropolitano" stadiums, where the other two quarterfinal matches will take place this week.

UEFA is aware of this and has already announced that the matches will go on as usual. However, with increased security forces.
