Swedish radio station RIX FM tried to put off the Portugal national team by making a loud noise outside their hotel.
Portugal currently have the advantage in their World Cup playoff tie against Sweden due to a 1-0 win in the first leg on Friday.
Before tonight's second leg, the local radio station turned up outside the team hotel with a karaoke system and numerous stage props, according to the Daily Mail.
The group are said to have begun their noisy session at around 7.15am.
