Malmo's head coach Age Hareide is angry after comments made by his goalkeeper about Celtic were lost in translation.
In an interview with a Swedish journalist, Johan Wiland appeared to call the Scottish Premiership side's players "pigs".
Ronny Deila's men are in Sweden for tomorrow night's second leg of their Champions League qualifying play-off, where they lead 3-2.
Hareide says it is annoying when things are misrepresented in the media as he said angrily in his pre-match press conference.
"If you pronounce the words correctly pig means grisar … to play like a pig, is to play dirty. It was a tough game but it was not a dirty game.
"A pig is something else in English than it is in Scandinavia. You have a word that starts with F and ends in K and you say it all the time. It means something else in Scandinavia. It is not swearing in Scandinavia. So you have to have respect for other languages.
"That is why I am upset with the press, you just translate things and then put them in headlines. The only thing I want from the press is to tell the truth. You have to have respect for languages and the places you travel to, to pronounce things correctly."
